Zuul is moving its container image hosting to quay.io. Update our docker-compose.yaml files to pull the images from this new location. Note we don't update zuul-registry as it hasn't updated yet. A followup change will update that container image location separately. Change-Id: Idce7df82e811490fa5d817682479161bd74cd848
Install, configure, and run zuul-preview.
