Prometheus - v2.40.0

This release introduces an experimental, native way of representing and storing histograms.

It can be enabled in Prometheus via --enable-feature=native-histograms to accept native histograms.
Enabling native histograms will also switch the preferred exposition format to protobuf.

To instrument your application with native histograms, use the v1.14.0 or later of client_golang and set the NativeHistogramBucketFactor in your HistogramOpts (1.1 is a good starting point).
Your existing histograms won't switch to native histograms until NativeHistogramBucketFactor is set.
