* 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.

* tsdb/{index,compact}: allow using custom postings encoding format

We would like to experiment with a different postings encoding format in
Thanos so in this change I am proposing adding another argument to
`NewWriter` which would allow users to change the format if needed.
Also, wire the leveled compactor so that it would be possible to change
the format there too.

* 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.

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.

Add a chunk size limit in bytes (#12054)
Add a chunk size limit in bytes

This creates a hard cap for XOR chunks of 1024 bytes.

The limit for histogram chunk is also 1024 bytes, but it is a soft limit as a histogram has a dynamic size, and even a single one could be larger than 1024 bytes.

This also avoids cutting new histogram chunks if the existing chunk has fewer than 10 histograms yet. In that way, we are accepting "jumbo chunks" in order to have at least 10 histograms in a chunk, allowing compression to kick in.

tsdb/agent: ensure that new series get written to WAL on rollback (#12592)
If a new series is introduced in a storage.Appender instance, that
series should be written to the WAL once the storage.Appender is closed,
even on Rollback.

Previously, new series would only be written to the WAL when calling
Commit. However, because the series is stored in memory regardless,
subsequent calls to Commit may write samples to the WAL which reference
a series ID which that was never written.

Related to #11589. It's likely that this fix also resolves this issue,
but we need more testing from users to see if the problem persists after
this fix; there may be more cases where samples get written to the WAL
in Prometheus Agent mode without the corresponding series record.

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.

beorn7 c3c7d44d84 lint: Adjust to the lint warnings raised by current versions of golint-ci
We haven't updated golint-ci in our CI yet, but this commit prepares
for that.

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.

beorn7 817a2396cb Name float values as "floats", not as "values"
In the past, every sample value was a float, so it was fine to call a
variable holding such a float "value" or "sample". With native
histograms, a sample might have a histogram value. And a histogram
value is still a value. Calling a float value just "value" or "sample"
or "V" is therefore misleading. Over the last few commits, I already
renamed many variables, but this cleans up a few more places where the
changes are more invasive.

Note that we do not to attempt naming in the JSON APIs or in the
protobufs. That would be quite a disruption. However, internally, we
can call variables as we want, and we should go with the option of
avoiding misunderstandings.

"Removing ableist language in code is important; it helps to create and

while emphasizing that we as developers select the most articulate,

The phrase sanity check is ableist, and unnecessarily references mental
health in our code bases. It denotes that people with mental illnesses
are inferior, wrong, or incorrect, and the phrase sanity continues to be
used by employers and other individuals to discriminate against these
people."

p.Help(), p.Unit(), p.Type() helpers, which retrieve the series name and
use it as the cache key. When checking for cache entries though, we used
p.Series() as the key, which included the metric name _with_ its labels.
That meant that we were never actually hitting the cache. We're fixing
this by utiling the __name__ internal label for correctly getting the
cache entries after they've been set by setHelp(), setType() or
setUnit().

For `BenchmarkLabelValuesWithMatchers()` and

* tsdb/agent: port grafana/agent#676

grafana/agent#676 fixed an issue where a loading a WAL with multiple
segments may result in ref ID collision. The starting ref ID for new
series should be set to the highest ref ID across all series records
from all WAL segments.

This fixes an issue where the starting ref ID was incorrectly set to the
highest ref ID found in the newest segment, which may not have any ref
IDs at all if no series records have been appended to it yet.
