Can ovirt_engine_find_bugs_gerrit be run against changed files, instead of all?

[Fabian Deutsch]

Hey,
I noted that ovirt_engine_find_bugs_gerrit eat's a lot of our builders
resources. I wondered if the job can be changed to only check changed
files, instead of the whole tree?
With git you can do
  git diff --name-only HEAD~1..HEAD
to retrieve the changed files between two versions.
