promql: fix some aggregations for histograms

This PR fixes the behaviour of `topk`,`bottomk`, `limitk` and `limit_ratio` with histograms. The fixed behaviour are as follows:
- For `topk` and `bottomk` histograms are ignored and add info annotations added.
- For `limitk` and `limit_ratio` histograms are included in the results(if applicable).

newtonne 88675710f9 Add support for utf8 names on `/v1/label/:name/values` endpoint
Previously, the api was evaluating this regex to determine if the label
name was valid or not:

14bac55a99/model/labels.go (L94)

However, I believe that the `IsValid()` function is what ought to be
used in the brave new utf8 era.

**Before**

```
$ curl localhost:9090/api/v1/label/host.name/values
{"status":"error","errorType":"bad_data","error":"invalid label name: \"host.name\""}
```

**After**

```
$ curl localhost:9090/api/v1/label/host.name/values
{"status":"success","data":["localhost"]}
```

It's very likely that I'm missing something here or you were already
planning to do this at some point but I just encountered this issue and
figured I'd give it a go.

TJ Hoplock 3e24e84172 fix!: stop unbounded memory usage from query log
Resolves: #15433

When I converted prometheus to use slog in #14906, I update both the
`QueryLogger` interface, as well as how the log calls to the
`QueryLogger` were built up in `promql.Engine.exec()`. The backing
logger for the `QueryLogger` in the engine is a
`util/logging.JSONFileLogger`, and it's implementation of the `With()`
method updates the logger the logger in place with the new keyvals added
onto the underlying slog.Logger, which means they get inherited onto
everything after. All subsequent calls to `With()`, even in later
queries, would continue to then append on more and more keyvals for the
various params and fields built up in the logger. In turn, this causes
unbounded growth of the logger, leading to increased memory usage, and
in at least one report was the likely cause of an OOM kill. More
information can be found in the issue and the linked slack thread.

This commit does a few things:

- It was referenced in feedback in #14906 that it would've been better
  to not change the `QueryLogger` interface if possible, this PR
proposes changes that bring it closer to alignment with the pre-3.0
`QueryLogger` interface contract
- reverts `promql.Engine.exec()`'s usage of the query logger to the
  pattern of building up an array of args to pass at once to the end log
call. Avoiding the repetitious calls to `.With()` are what resolve the
issue with the logger growth/memory usage.
- updates the scrape failure logger to use the update `QueryLogger`
  methods in the contract.
- updates tests accordingly
- cleans up unused methods

Builds and passes tests successfully. Tested locally and confirmed I
could no longer reproduce the issue/it resolved the issue.

beorn7 4b573e0521 promql: Fix subqueries to be really left-open
Previously, we managed to get rid of the sample on the left bound
later, so the problem didn't show up in the framework tests. But the
subqueries were still evaluation with the sample on the left bound,
taking space and showing up if returning the subquery result directly
(without further processing through PromQL like in all the framework
tests).

promqltest: Complete the tests for info annotations (#15429)
promqltest: Complete the tests for info annotations

So far, we did not test for the _absence_ of an info annotation
(because many tests triggered info annotations, which we haven't taken
into account so far).

The test for info annotations was also missed for range queries.

This completes the tests for info annotations (and refactors the many
`if` statements into a somewhat more compact `switch` statement).

It fixes most tests to not emit an info annotation anymore. Or it
changes the `eval` to `eval_info` where we actually want to test for
the info annotation.

It also fixes a few spelling errors in comments.

I'd like to use queries of the form "x and on() (vector(y)==1)" to be
able to include and exclude series for dashboards. This helps migration
to native histograms in dashboards by using a dashboard variable to
set "y" to either -1 or 1 to exclude or include the result.

Fix stddev/stdvar when aggregating histograms, NaNs, and infinities (#14941)
promql: Fix stddev/stdvar when aggregating histograms, NaNs, and Infs

Native histograms are ignored when calculating stddev or stdvar.

However, for the first series of each group, a `groupedAggregation` is
always created. If the first series that was encountered is a histogram
then it acts as the equivalent of a 0 point.

This change creates the first `groupedAggregation` with the `seen` field set to `false` if the point is a
histogram, thus ignoring it like the rest of the aggregation function does. A new `groupedAggregation`
will then be created once an actual float value is encountered.

This commit also sets the `floatValue` field of the `groupedAggregation` to `NaN`, if the first
float value of a group is `NaN` or `±Inf`, so that the outcome is consistently `NaN` once those
values are in the mix.

(The added tests fail without this change).

The `info` function is an experiment to improve UX

`info` has to be enabled via the feature flag `--enable-feature=promql-experimental-functions`.

This MVP of info simplifies the implementation by assuming:
* Only support for the target_info metric
* That target_info's identifying labels are job and instance

Also:
* Encode info samples' original timestamp as sample value
* Deduce info series select hints from top-most VectorSelector
