beorn7 ad7d1aed99 Phase out native histogram feature flag 
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.
