docs/configuration: clarify OpenStack metadata labels (#14149) 
On several occasions, users assumed that the
`__meta_openstack_tag_<key>` labels were about tags [1] instead of
metadata [2]. While we can't really change the Prometheus label name, we
can at least clarify in the documentation what's the information carried
in the label.

Check context every 128 labels instead of 100 (#14118) 
Follow up on https://github.com/prometheus/prometheus/pull/14096

As promised, I bring a benchmark, which shows a very small improvement
if context is checked every 128 iterations of label instead of every
100.

It's much easier for a computer to check modulo 128 than modulo 100.
This is a very small 0-2% improvement but I'd say this is one of the
hottest paths of the app so this is still relevant.

tsdb: check for context cancel before regex matching postings (#14096) 
* tsdb: check for context cancel before regex matching postings

Regex matching can be heavy if the regex takes a lot of cycles to
evaluate and we can get stuck evaluating postings for a long time
without this fix. The constant checkContextEveryNIterations=100
may be changed later.

Bryan Boreham 10eb23bd6b [TEST] Rules: Sleep 15ms to fit Windows behaviour better 
On Windows, Go will sleep 15ms if you ask for less.  TestAsyncRuleEvaluation
compares actual delay to the nominal time, so using 15ms should work
better on Windows, and be hardly noticeable elsewhere.

[ENHANCEMENT] TSDB: Optimize querying with regexp matchers 
Add method `PostingsForLabelMatching` to `tsdb.IndexReader`, to obtain postings for labels with a certain name and values accepted by a provided callback, and use it from `tsdb.PostingsForMatchers`.
The intention is to optimize regexp matcher paths, especially not having to load all label values before matching on them.

Plus tests, and refactor some `tsdb/index.Reader` methods.

Benchmarking shows memory reduction up to ~100%, and speedup of up to ~50%.
