Bodhi: update messaging queues for change in 5.7.1
    
    In 5.7.1, Bodhi changed from consuming greenwave.decision.update
    messages to consuming resultsdb and waiverdb messages, when
    deciding whether to update an update's gating status. We need to
    subscribe to the correct message queues for that to work properly.
