For: #14355
This commit updates Prometheus to adopt stdlib's log/slog package in
favor of go-kit/log. As part of converting to use slog, several other
related changes are required to get prometheus working, including:
- removed unused logging util func `RateLimit()`
- forward ported the util/logging/Deduper logging by implementing a small custom slog.Handler that does the deduping before chaining log calls to the underlying real slog.Logger
- move some of the json file logging functionality to use prom/common package functionality
- refactored some of the new json file logging for scraping
- changes to promql.QueryLogger interface to swap out logging methods for relevant slog sugar wrappers
- updated lots of tests that used/replicated custom logging functionality, attempting to keep the logical goal of the tests consistent after the transition
- added a healthy amount of `if logger == nil { $makeLogger }` type conditional checks amongst various functions where none were provided -- old code that used the go-kit/log.Logger interface had several places where there were nil references when trying to use functions like `With()` to add keyvals on the new *slog.Logger type

api: Improve doc comments for v1.MinTime and v1.MaxTime
While investigated something mostly unrelated, I got nerd-sniped by
the calculation of v1.MinTime and v1.MaxTime. The seemingly magic
number in there (62135596801) needed an explanation. While looking for
it, I found out that the offsets used here are actually needlessly
conservative. Since the timestamps are so far in the past or future,
respectively, that there is no practical impact, except that the
calculation is needlessly obfuscated. However, we won't change the
values now to not cause any confusion for users of this code. Still, I
think the doc comment should explain the circumstances so nobody gets
nerd-sniped again as I did today.
For the record: 62135596800 is the difference in seconds between 0001-01-01 00:00:00 (Unix time zero point) and 1971-01-01 00:00:00 (Go time zero point) in the Gregorian calendar. If "Prometheus time" were in seconds (not milliseconds), that difference would be relevant to prevent over-/underflow when converting from "Prometheus time" to "Go time".

This switches from the prehistoric EventSource API to the more modern
fetch-event-source package. That packages gives us full control over the
retries.
It also gives us the opportunity to close the event source when the
browser tab is hidden, saving resources.

This commit introduces a new `/api/v1/notifications/live` endpoint that
utilizes Server-Sent Events (SSE) to stream notifications to the web UI.
This is used to display alerts such as when a configuration reload
has failed.
I opted for SSE over WebSockets because SSE is simpler to implement and
more robust for our use case. Since we only need one-way communication
from the server to the client, SSE fits perfectly without the overhead
of establishing and maintaining a two-way WebSocket connection.
When the SSE connection fails, we go back to a classic
/api/v1/notifications API endpoint.
This commit also contains the required UI changes for the new Mantine UI.

'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.

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

* 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.

Also, wire the leveled compactor so that it would be possible to change

* 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.

* Fix last_over_time for native histograms
The last_over_time retains a histogram sample without making a copy.

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.

Conditions are ANDed inside the same matcher but matchers are ORed
Including unit tests for "promtool tsdb dump".
Refactor some matchers scraping utils.

They are used in multiple repos, so common is a better place for them.
Several packages now don't depend on `model/textparse`, e.g.
`storage/remote`.
Also remove `metadata` struct from `api.go`, since it was identical to
a struct in the `metadata` package.

Too confusing to have `MetadataList` and `ListMetadata`, etc.
I standardised on the ones which are in an interface.

* web/api: optimize labelnames/values with 1 set of matchers
If there is exactly one set of matchers provided, we can skip adding
the results to a map and getting them back out again.

Add unit tests for Web API's query endpoint (GET/POST).
Also modify the endpoint handler to use context.WithDeadline instead of
context.WithTimeout, so the deadline is deterministic for the tests.

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.

It's possible (quite common on Kubernetes) to have a service discovery
return thousands of targets then drop most of them in relabel rules.
The main place this data is used is to display in the web UI, where
you don't want thousands of lines of display.
The new limit is `keep_dropped_targets`, which defaults to 0
for backwards-compatibility.

Convert QueryOpts to an interface so that downstream projects like
https://github.com/thanos-community/promql-engine could extend the query
options with engine specific options that are not in the original
engine.
Will be used to enable query analysis per-query.
