Note: This is deliberately an incompatible change. Since we have never used histograms in remote read/write yet, there is no point in keeping compatibility. This _is_, however, compatible to the state in the main branch. This commit flattens the bucket message into top-level fields. This has the disadvantage of now having two triples of fields prefixed with `negative_...` or `positive_...`. However, with this structure, we save one tag on the wire. And, perhaps more importantly, we mirror the structure of the `histogram.Histogram` Go type. This commit also adjusts `repeated` fields to use names in the plural form, as it is also the case for the fields that already existed. This also adds a doc comment to `HistogramProtoToHistogram` and changes its return type to a pointer (which is more convenient and probably more efficient). Signed-off-by: beorn7 <beorn@grafana.com>
