bug 1438735 - balrog scriptworker push and schedule support. r=bhearsum - add balrog submit-toplevel - this replaces the final portion of the updates builder. - rename balrog transform to balrog_submit, because it's for balrog locale submission - make this default to the 'promote' phase. balrog and beetmover currently take the current phase, which isn't always the wanted behavior. - rename balrog publish to balrog schedule - add balrog secondary push and secondary scheduling, for RCs - remove the release_updates transforms - make the task.py balrog transforms smarter - get rid of the release_balrog_publishing transforms; ad a generic worker_type transform - add BALROG_ACTIONS to scriptworker.py - add get_balrog_action_scope() - remove the unused balrog channel scopes MozReview-Commit-ID: 369ACiOAd5F
