"""Adds build info to perf results and uploads them.

The tests don't know which bot executed the tests or at what revision, so we
need to take their output and enrich it with this information. We load the proto
from the tests, add the build information as shared diagnostics and then
upload it to the dashboard.

This script can't be in recipes, because we can't access the catapult APIs from
there. It needs to be here source-side.
