This script will be used when tests write proto-backed JSON. It still
has to reside source-side because we need to access the catapult Python
API to get at HistogramSet and reserved_infos, etc.
WebRTC tests will write proto-backed JSON, and this script can read
it because the Histogram class has been made capable of doing it.
Build information diagnostics are added, and then we upload in the
old JSON format (the dashboard can read the new format as well, but
there's no reason to implement export to the new format at this point).
We could imagine more outlandish solutions where the test binaries
themselves do the uploading, but then we would have to pass the
build information to them, and they would have to upload from the
shards. Alternatively, we could pass build information to tests so
they write it right into the histograms.
This solution is probably the best one for now since it's
1) consistent with how Chromium does it
2) flexible in the right ways
3) we don't have to worry if uploading from shards even works.

This effectively makes WebRTC upload histogram sets instead of Chart
JSON. Histogram sets is the newest format used by Chromium. I'm doing
this because it's nice to use the most modern thing, but mostly because
it's the default for PinPoint. This means I don't have to implement and
support a new read quest for Chart JSON.
This script has to be source side, because we need third_party/catapult
to write correct histograms. This script will be called from recipes.
I also considered generating histogram JSON directly in
test/testsupport/perf_test.cc, which could have avoided this conversion
from Chart JSON to histogram sets, but I can't because there is no C++
API for histogram sets.
