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.

Making changes to textparse lexers
In the rare case that you need to update the textparse lexers, edit promlex.l or openmetricslex.l and then run the following command:
golex -o=promlex.l.go promlex.l
Note that you need golex installed:
go get -u modernc.org/golex
