The gitlab driver sets change.files to None on branch push events. Like every other system, it also emits branch push events after merging merge requests. When the scheduler encounters a branch updated event with files.None, it assumes the worst and performs a tenant reconfiguration. This means that Zuul performs a tenant reconfiguration after every single MR is merged. Gitlab supplies a list of changed files on push events. This change modifies the gitlab driver to do that. This mirrors what is done in the github driver. Change-Id: Ia6651048eea7f183ee0a65b6e8de83fdf892c9a7
