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.

* Fix issue where comparison operations with `bool` modifier and native histograms return histograms rather than 0 or 1
* Don't emit anything for comparisons between floats and histograms when `bool` modifier is used
* Don't emit anything for comparisons between floats and histograms when `bool` modifier is used between a vector and a scalar

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.

Enable the `auto-gomaxprocs` feature flag by default.
* Add command line flag `--no-auto-gomaxprocs` to disable.

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.
