beorn7 87351f2318 prompb: Modify layout of histograms
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).

Remote Write Adapter Example

This is a simple example of how to write a server to receive samples from the remote storage output.

To use it:

go build
./example_write_adapter

...and then add the following to your prometheus.yml:

remote_write:
  - url: "http://localhost:1234/receive"

Then start Prometheus:

./prometheus
