docs: Fix type of the histogram_quantile function (#7666)

cf698f71e5 Add an explanation for the quantile aggregation operator 
Sadly, just linking to the Histogram best practice document, as done
for `histogram_quantile`, would be confusing here because the best
practice document only deals with quantiles in the context of
Histograms and Summaries, which is very different from the context of
the `quantile` aggregator and `quantile_over_time` function, which is
already a source of a lot of confusion.

Thus, I think the least bad solution is to add a short explanation in
this section directly. There isn't even a good resource on the
internet we can link to. A lot of statisticians use φ-quantiles, but
they don't have a generally accepted name for it.

I have added the explanation after the other detailed explanations of
`count_values`, `topk` and `bottomk`. I think that fits quite nicely
into the flow.

e1f2da74a3 api: provide metadata for a single metric 
This adds support for a new query param on the new `api/v1/metadata`
endpoint that provides metadata for a specified metric via the V1 API.

It collapses metadata that is equal across all targets, and aggregates
under the same metric name the ones that differ.

0a0a228db3 api: provide per metric metadata (#6420) 
* api: provide per metric metadata

This adds a new endpoint that provides per metric metadata via the V1 API.

It collapses metadata that is equal across all targets, and aggregates under the same metric name the ones that differ.

* Allow tests to be asserted on response length

Some tests e.g. limit on API responses, don't require an assertion on
equality.

This allows us to assert against response length instead of
equality.

cae4538b3e Docs: state that all regular expressions are RE2. (#3518) 
We already mentioned that regular expressions are RE2 for
[relabeling][0], but left open what the regular expression syntax
anywhere else is.

In the querying examples and reference, make it explicit that _all_
regular expressions are RE2.

This endpoint has moved to /api/v2 (with somewhat different properties)
in Prometheus 2.0 and should now be part of a separate admin API page.
