Comment 27 for bug 1518430

Marked as verifcation-done as this has passed tests on xenial and yakkety. We perform regression testing by juju deploying two openstack clouds, one against -proposed and one against -updates, and we then run tempest integration smoke tests[1] to verify those deployed clouds, and evaluate any differences in results.
