The upgrade to prometheus/otlptranslator@7f02967de0 fixes two label
name translation bugs, when in legacy name translation mode:
* 'key' is no longer prefixed when label names start with an underscore
* Multiple consecutive underscores are combined into one

The detailed plan for this is laid out in
https://github.com/prometheus/prometheus/issues/16572 .
This commit adds a global and local scrape config option
`scrape_native_histograms`, which has to be set to true to ingest
native histograms.
To ease the transition, the feature flag is changed to simply set the
default of `scrape_native_histograms` to true.
Further implications:
- The default scrape protocols now depend on the
`scrape_native_histograms` setting.
- Everywhere else, histograms are now "on by default".
Documentation beyond the one for the feature flag and the scrape
config are deliberately left out. See
https://github.com/prometheus/prometheus/pull/17232 for that.

avg_over_time already correctly checked the counter reset hint fo all
histograms, but in sum_over_time, the 1st histogram was missed. In
both cases, the 1st histogram is processed outside the loop.

Fixes#17308.
As explained adding the warn-annotation about conflicting counter
reset hints doesn't happen consistently. Furthermore, because of
incremental mean calculation being used so far (which includes
subtraction), avg calculation always created gauge histograms.
The fix is to make Sub behave like Add WRT counter reset handling, and
then set the result of a subtraction to gauge explicitly in actual
PromQL subtraction (rather than using Sub for something else, like
incremental mean calculation). Also, track the presence of a
CounterReset hint and a NotCounterReset hint separately for the
entirety of aggregated histograms and create the warn-annotation based
on that.
As a minor fix, this commit also consistently creates the warn
annotation in aggregation to be about "aggregation" rather than
"subtraction" or "addition", because the latter are just internal
operations within the aggregation, which is not of interest for the
user.
