A `HistogramTestExpression` was missed in one case, which made the
formatting weird in case a histogram got unexpectedly returned.

Ensure metric name is present on histogram_quantile annotations
Previously the series __name__ label was dropped before the annotation
was emitted causing the annotation message to have a blank value.
This fix also allows delayed name removal for classic histograms.
This also adds a test for malformed le label
This annotation could be split into two to be clearer for the user
(one for missing, and one for malformed). This is outside of the scope
of this change.

This also improves the documentation in the following ways:
- Clarifies that `eval` requires no annotations.
- Clarifies that `eval_ordered` ignores annotations.
- Clarifies that `eval_ordered` does not work with matrix returns
(which could very well be created by instant queries).
- Clarifies that there are more `eval` commands than just `eval`.
- Improves wording for `eval_ordered`.
- Replaces `...` by the typographical correct `…`.
- Fixes a numerical error in an example.

Besides making eval_ordered ignore annotations, this does the following:
- Adds a test to verify that eval_ordered indeed ignores an info
annotations now, while eval complains about it, eval_info recognizes
it and, eval_warn flags the missing of the warn annotation.
- Refactors the annotation check into its own method.
- Moves closing of the query to the appropriate place where it wasn't
so far.

Improves upon #15434, better resolves#15433.
This commit introduces a few changes to ensure safer handling of the
JSONFileLogger:
- the JSONFileLogger struct now implements the slog.Handler interface,
so it can directly be used to create slog Loggers. This pattern more
closely aligns with upstream slog usage (which is generally based around
handlers), as well as making it clear that devs are creating a whole new
logger when interacting with it (vs silently modifying internal configs
like it did previously).
- updates the `promql.QueryLogger` interface to be a union of the
methods of both the `io.Closer` interface and the `slog.Handler`
interface. This allows for plugging in/using slog-compatible loggers
other than the JSONFileLogger, if desired (ie, for downstream projects).
- introduces new `scrape.FailureLogger` interface; just like
`promql.QueryLogger`, it is a union of `io.Closer` and `slog.Handler`
interfaces. Similar logic applies to reasoning.
- updates tests where needed; have the `FakeQueryLogger` from promql's
engine_test implement the `slog.Handler`, improve JSONFileLogger test
suite, etc.

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).

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.
