remote write 2.0: sync with main branch (#13510)
* consoles: exclude iowait and steal from CPU Utilisation

'iowait' and 'steal' indicate specific idle/wait states, which shouldn't
be counted into CPU Utilisation. Also see
https://github.com/prometheus-operator/kube-prometheus/pull/796 and
https://github.com/kubernetes-monitoring/kubernetes-mixin/pull/667.

Per the iostat man page:

%idle
    Show the percentage of time that the CPU or CPUs were idle and the
    system did not have an outstanding disk I/O request.

%iowait
     Show the percentage of time that the CPU or CPUs were idle during
     which the system had an outstanding disk I/O request.

%steal
     Show the percentage of time spent in involuntary wait by the
     virtual CPU or CPUs while the hypervisor was servicing another
     virtual processor.

* tsdb: shrink txRing with smaller integers

4 billion active transactions ought to be enough for anyone.

Signed-off-by: Bryan Boreham <bjboreham@gmail.com>

* tsdb: create isolation transaction slice on demand

When Prometheus restarts it creates every series read in from the WAL,
but many of those series will be finished, and never receive any more
samples. By defering allocation of the txRing slice to when it is first
needed, we save 32 bytes per stale series.

* Get VM Scale Set NIC (#13283)

Calling `*armnetwork.InterfacesClient.Get()` doesn't work for Scale Set
VM NIC, because these use a different Resource ID format.

Use `*armnetwork.InterfacesClient.GetVirtualMachineScaleSetNetworkInterface()`
instead.  This needs both the scale set name and the instance ID, so
add an `InstanceID` field to the `virtualMachine` struct.  `InstanceID`
is empty for a VM that isn't a ScaleSetVM.

* fix(discovery): allow requireUpdate util to timeout in discovery/file/file_test.go.

The loop ran indefinitely if the condition isn't met.

Before, each iteration created a new timer channel which was always outpaced by
the other timer channel with smaller duration.

minor detail: There was a memory leak: resources of the ~10 previous timers were
constantly kept. With the fix, we may keep the resources of one timer around for defaultWait
but this isn't worth the changes to make it right.

* storage: skip merging when no remote storage configured

Prometheus is hard-coded to use a fanout storage between TSDB and
a remote storage which by default is empty.
This change detects the empty storage and skips merging between
result sets, which would make `Select()` sort results.

Bottom line: we skip a sort unless there really is some remote storage
configured.

* Optimize histogram iterators (#13340)

Optimize histogram iterators

Histogram iterators allocate new objects in the AtHistogram and
AtFloatHistogram methods, which makes calculating rates over long
ranges expensive.

In #13215 we allowed an existing object to be reused
when converting an integer histogram to a float histogram. This commit follows
the same idea and allows injecting an existing object in the AtHistogram and
AtFloatHistogram methods. When the injected value is nil, iterators allocate
new histograms, otherwise they populate and return the injected object.

The commit also adds a CopyTo method to Histogram and FloatHistogram which
is used in the BufferedIterator to overwrite items in the ring instead of making
new copies.

Note that a specialized HPoint pool is needed for all of this to work 
(`matrixSelectorHPool`).

* Labels: Add DropMetricName function, used in PromQL (#13446)

This function is called very frequently when executing PromQL functions,
and we can do it much more efficiently inside Labels.

In the common case that `__name__` comes first in the labels, we simply
re-point to start at the next label, which is nearly free.

`DropMetricName` is now so cheap I removed the cache - benchmarks show
everything still goes faster.

* Name @beorn7 and @krajorama as maintainers for native histograms

I have been the de-facto maintainer for native histograms from the
beginning. So let's put this into MAINTAINERS.md.

In addition, I hereby proposose George Krajcsovits AKA Krajo as a
co-maintainer. He has contributed a lot of native histogram code, but
more importantly, he has contributed substantially to reviewing other
contributors' native histogram code, up to a point where I was merely
rubberstamping the PRs he had already reviewed. I'm confident that he
is ready to to be granted commit rights as outlined in the
"Maintainers" section of the governance:
https://prometheus.io/governance/#maintainers

According to the same section of the governance, I will announce the
proposed change on the developers mailing list and will give some time
for lazy consensus before merging this PR.

* Fix last_over_time for native histograms

The last_over_time retains a histogram sample without making a copy.
This sample is now coming from the buffered iterator used for windowing functions,
and can be reused for reading subsequent samples as the iterator progresses.

I would propose copying the sample in the last_over_time function, similar to
how it is done for rate, sum_over_time and others.

* Add ShardedPostings() support to TSDB (#10421)

This PR is a reference implementation of the proposal described in #10420.

In addition to what described in #10420, in this PR I've introduced labels.StableHash(). The idea is to offer an hashing function which doesn't change over time, and that's used by query sharding in order to get a stable behaviour over time. The implementation of labels.StableHash() is the hashing function used by Prometheus before stringlabels, and what's used by Grafana Mimir for query sharding (because built before stringlabels was a thing).

Follow up work
As mentioned in #10420, if this PR is accepted I'm also open to upload another foundamental piece used by Grafana Mimir query sharding to accelerate the query execution: an optional, configurable and fast in-memory cache for the series hashes.

Change ChunkReader.Chunk() to ChunkOrIterable()
The ChunkReader interface's Chunk() has been changed to ChunkOrIterable(). 

This is a precursor to OOO native histogram support - with OOO native histograms, the chunks.Meta passed to Chunk() can result in multiple chunks being returned rather than just a single chunk (e.g. if oooMergedChunk has a counter reset in the middle). 

To support this, ChunkOrIterable() requires either a single chunk or an iterable to be returned. If an iterable is returned, the caller has the responsibility of converting the samples from the iterable into possibly multiple chunks. The OOOHeadChunkReader now returns an iterable rather than a chunk to prepare for the native histograms case. Also as a beneficial side effect, oooMergedChunk and boundedChunk has been simplified as they only need to implement the Iterable interface now, not the full Chunk interface.

Add warnings (and annotations) to PromQL query results (#12152)
Return annotations (warnings and infos) from PromQL queries

This generalizes the warnings we have already used before (but only for problems with remote read) as "annotations".

Annotations can be warnings or infos (the latter could be false positives). We do not treat them different in the API for now and return them all as "warnings". It would be easy to distinguish them and return infos separately, should that appear useful in the future.

The new annotations are then used to create a lot of warnings or infos during PromQL evaluations. Partially these are things we have wanted for a long time (e.g. inform the user that they have applied `rate` to a metric that doesn't look like a counter), but the new native histograms have created even more needs for those annotations (e.g. if a query tries to aggregate float numbers with histograms).

The annotations added here are not yet complete. A prominent example would be a warning about a range too short for a rate calculation. But such a warnings is more tricky to create with good fidelity and we will tackle it later.

Another TODO is to take annotations into account when evaluating recording rules.

beorn7 5b53aa1108 style: Replace else if cascades with switch
Wiser coders than myself have come to the conclusion that a `switch`
statement is almost always superior to a statement that includes any
`else if`.

The exceptions that I have found in our codebase are just these two:

* The `if else` is followed by an additional statement before the next
  condition (separated by a `;`).
* The whole thing is within a `for` loop and `break` statements are
  used. In this case, using `switch` would require tagging the `for`
  loop, which probably tips the balance.

Why are `switch` statements more readable?

For one, fewer curly braces. But more importantly, the conditions all
have the same alignment, so the whole thing follows the natural flow
of going down a list of conditions. With `else if`, in contrast, all
conditions but the first are "hidden" behind `} else if `, harder to
spot and (for no good reason) presented differently from the first
condition.

I'm sure the aforemention wise coders can list even more reasons.

In any case, I like it so much that I have found myself recommending
it in code reviews. I would like to make it a habit in our code base,
without making it a hard requirement that we would test on the CI. But
for that, there has to be a role model, so this commit eliminates all
`if else` occurrences, unless it is autogenerated code or fits one of
the exceptions above.

There are a lot of new warnings, and it is mostly because the "revive"
linter got updated. I agree with most of the new warnings, mostly
around not naming unused function parameters (although it is justified
in some cases for documentation purposes – while things like mocks are
a good example where not naming the parameter is clearer).

I'm pretty upset about the "empty block" warning to include `for`
loops. It's such a common pattern to do something in the head of the
`for` loop and then have an empty block. There is still an open issue
about this: https://github.com/mgechev/revive/issues/810 I have
disabled "revive" altogether in files where empty blocks are used
excessively, and I have made the effort to add individual
`// nolint:revive` where empty blocks are used just once or twice.
It's borderline noisy, though, but let's go with it for now.

I should mention that none of the "empty block" warnings for `for`
loop bodies were legitimate.

Bryan Boreham cf92cd2688 tsdb: sort values for Postings only when required
In the head and in v1 postings on disk, it makes no difference whether
postings are sorted. Only for v2 does the code step through in order.
So, move the sorting to where it is required, and thus skip it entirely
in the head.

Label values in on-disk blocks are already sorted, but `slices.Sort` is
very fast on already-sorted data so we don't bother checking.

Bryan Boreham 10b27dfb84 Simplify IndexReader.Series interface
Instead of passing in a `ScratchBuilder` and `Labels`, just pass the
builder and the caller can extract labels from it. In many cases the
caller didn't use the Labels value anyway.

Now in `Labels.ScratchBuilder` we need a slightly different API: one
to assign what will be the result, instead of overwriting some other
`Labels`. This is safer and easier to reason about.

Bryan Boreham d3d96ec887 tsdb/index: use ScratchBuilder to create Labels
This necessitates a change to the `tsdb.IndexReader` interface:
`index.Reader` is used from multiple goroutines concurrently, so we
can't have state in it.

We do retain a `ScratchBuilder` in `blockBaseSeriesSet` which is
iterator-like.

Bryan Boreham 3c7de69059 storage: allow re-use of iterators
Patterned after `Chunk.Iterator()`: pass the old iterator in so it

(This commit does not do any re-use; it is just changing all the method
signatures so re-use is possible in later commits.)

Inverting the test for chunks deleted by tombstones makes all three
rejections consistent, and also avoids the case where a chunk is
excluded but still causes `trimFront` or `trimBack` to be set.

Bryan Boreham 0c05f95e92 tsdb: use smaller allocation in blockBaseSeriesSet
This reduces garbage, hence goes faster, when a short time range is
required compared to the amount of chunks in the block. For example
recording rules and alerts often look only at the last few minutes.

Replace sort.Strings and sort.Ints with faster slices.Sort (#11318)
Use new experimental package `golang.org/x/exp/slices`.

slices.Sort works on values that are directly comparable, like ints,
so avoids the overhad of an interface call to `.Less()`.

Left tests unchanged, because they don't need the speed and it may be
a cross-check that slices.Sort gives the same answer.
