This error is emitted in cleanupMetricLabels, but is skipped if

beorn7 9f6c1d9cd3 promqltest: Small formatting improvement for native histograms
A `HistogramTestExpression` was missed in one case, which made the
formatting weird in case a histogram got unexpectedly returned.

beorn7 2581c7d057 promql: fix rate calculation with a counter reset after the 1st histogram
If a rate (or increase) is calculated on native histograms, and there
is a counter reset between the 1st and 2nd histogram, we never have to
touch the 1st histogram, so it doesn't even matter if it has an
incompatible bucket layout. So we should not error out in that case.

This simply nulls out the 1st histogram in that case.

beorn7 d9a80a91e3 docs: Document eval_warn and eval_info
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.

beorn7 7687661453 promqltest: make eval_ordered ignore annotations
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.

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).

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.

This converts `TestNativeHistogram_SubOperator` to the promql testing framework. It also removes `TestNativeHistogram_Sum_Count_Add_AvgOperator`, which got converted earlier.

* tests(promql/testdata): add regression test for and-on

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.

In general aim for the happy case when the exposer lists the buckets
in ascending order.

Use Compact(2) to compact the result of nhcb convert.

This is more in line with how client_golang optimizes spans vs
buckets.
