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
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.

Instead of allocating ListPostings pointers one by one, allocate a slice
and take pointers from that. It's faster, and also generates less
garbage (NewListPostings is one of the top offenders in number of
allocations).

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.

Simple follow-up to #13620. Modify `tsdb.PostingsForMatchers` to use the optimized tsdb.IndexReader.PostingsForLabelMatching method also for inverse matching.
Introduce method `PostingsForAllLabelValues`, to avoid changing the existing method.
The performance is much improved for a subset of the cases; there are up to
~60% CPU gains and ~12.5% reduction in memory usage.
Remove `TestReader_InversePostingsForMatcherHonorsContextCancel` since
`inversePostingsForMatcher` only passes `ctx` to `IndexReader` implementations now.

* Don't emit anything for comparisons between floats and histograms when `bool` modifier is used

When a remote-write is executed towards a host name that is resolved to multiple IP addresses, this PR introduces a possibility to force creation of new connections used for the remote-write request to a randomly chosen IP address from the ones corresponding to the host name. The default behavior remains unchanged, i.s., the IP address used for the connection creation remains the one chosen by Go.
This is an experimental feature, it is disabled by default.

It was crashing due to uninitialized metrics, and not terminating due to
incorrectly reading segment names.
We need to export `SetMetrics` to avoid the first problem.

When we had a syntax error but restored the old file, we did not
re-trigger the config reload, so the config reload metric was showing
that config reload was unsucessful.
I made magic to handle logs in cmd/prometheus.
For now it is a separate file so we can backport this easily.
I will generalize the helper in another PR.
