While investigating lock contention on `MemPostings`, we saw that lots
of locking is happening in `LabelValues` and
`PostingsForLabelsMatching`, both copying the label values slices while
holding the mutex.
This adds an extra map that holds an append-only label values slice for
each one of the label names. Since the slice is append-only, it can be
copied without holding the mutex.

Instead of allocating ListPostings pointers one by one, allocate a slice
and take pointers from that. It's faster, and also generates less
garbage (NewListPostings is one of the top offenders in number of
allocations).

[PERF] TSDB: Optimize inverse matching ( #14144 )
...
Simple follow-up to #13620 . Modify `tsdb.PostingsForMatchers` to use the optimized tsdb.IndexReader.PostingsForLabelMatching method also for inverse matching.
Introduce method `PostingsForAllLabelValues`, to avoid changing the existing method.
The performance is much improved for a subset of the cases; there are up to
~60% CPU gains and ~12.5% reduction in memory usage.
Remove `TestReader_InversePostingsForMatcherHonorsContextCancel` since
`inversePostingsForMatcher` only passes `ctx` to `IndexReader` implementations now.

MemPostings.Delete(): make pauses to unlock and let the readers read ( #15242 )
...
This introduces back some unlocking that was removed in #13286 but in a
more balanced way, as suggested by @pracucci.
For TSDBs with a lot of churn, Delete() can take a couple of seconds,
and while it's holding the mutex, reads and writes are blocked waiting
for that mutex, increasing the number of connections handled and memory
usage.
This implementation pauses every 4K labels processed (note that also
compared to #13286 we're not processing all the label-values anymore,
but only the affected ones, because of #14307 ), makes sure that it's
possible to get the read lock, and waits for a few milliseconds more.

* Fix MemPostings.{Add,Get} data race
We can't modify the postings list that are held in MemPostings as they
might already be in use by some readers.
* Modify BenchmarkHeadStripeSeriesCreate to have common labels
If there are no common labels on the series, we don't excercise the
ordering part of MemSeries, as we're just creating slices of one element
for each label value.

TSDB head: fix race between AppendHistogram and Commit
...
Move writing memSeries lastHistogramValue and lastFloatHistogramValue
after series creation under lock.
The resulting code isn't totally correct in the sense that we're setting
these values before Commit() , so they might be overwritten/rolled back
later.
Also Append of stale sample checks the values without lock, so there's
still a potential race.
The correct solution would be to set these only in Commit() which we
actually do, but then Commit() would also need to process samples in
order and not floats first, then histograms, then float histograms - which
leads to not knowing what stale marker to write for histograms.

chore!: adopt log/slog, remove go-kit/log
...
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

Fix missing histogram copy in sampleRing
...
The specialized version of sample add to the ring:
func addH(s hSample, buf []hSample, r *sampleRing) []hSample
func addFH(s fhSample, buf []fhSample, r *sampleRing) []fhSample
already correctly copy histogram samples from the reused hReader, fhReader
buffers, but the generic version does not. This means that the
data is overwritten on the next read if the sample ring has seen histogram
and float samples at the same time and switched to generic mode.
The `genericAdd` function (which was commented anyway) is by now quite
different from the specialized functions so that this commit deletes
it.

Process MemPostings.Delete() with GOMAXPROCS workers
...
We are still seeing lock contention on MemPostings.mtx, and MemPostings.Delete() is by far the most expensive operation on that mutex.
This adds parallelism to that method, trying to reduce the amount of time we spend with the mutex held.

TSDB: Simplify benchmark regexps
...
Several regexps were coded like `"^.*$"`, which is an unnatural
formulation nobody is likely to use. Inside `NewMatcher`, `^` and `$`
are added anyway, which makes the form in the benchmark redundant.
It even printed it out in the expected way.
