#3254: gitlab merge request webhook should trigger a try build

 gitlab is the new hotness, and its users want to see test results
 magically pop up as review comments on merge requests.  Ideally they want
 to be able to paste the same webhook url into multiple projects and have
 it just work.

 buildbot does have gitlab webhook support, but only handles commits, not
 merge requests.

 Here's a standalone rough draft I'm starting to use:

 Once it's polished maybe it'd be worth including in contrib, but it'd be
 even better to integrate one into buildbot's existing gitlab webhook
 handler.
