First part is to support automated builds on git pushes also with gitlab, similar to what we do already with github.com. This means OBS would get notificated in a save way to refetch sources and start build on each commit.

Second part is to support automated branching when a pull request gets created. This allows CI similar to travis on pull requests.

Third part is integration of build results into gitlab. This way the developer don't need to leave gitlab interfaces after initial setup.
