With buildbot-nine, if you don't mind diving into the sql database model,
you are only a few left join away from getting that information.
Having a rest api that create the join for you is something that we need to
work on in the Gsoc.

With buildbot-eight, you need to parse the whole history of pickles, and
that is a pain. You can do that via the json api and this is extremely slow.
Some people are having nightly scripts to dump those pickles in a database
specially created for their metrics.
