 Blocks #2648

 `master/buildbot/status/status_gerrit.py` is designed to submit build
 results on a gerrit patch back to gerrit.  However, it's still mostly
 expecting the old Status hierarchy to exist, rather than the new Data API.

  It needs to be rewritten to listen for appropriate events from the Data
 API and submit them to Gerrit, with any additional information fetched
 through the Data API's "get" method.
