Public bug reported: I've only seen this on zesty deployments (things appear to be OK on xenial); the net result of these slow calls is that network setup ops for instances take along time to complete; this results in failed instance launches (and as a result failed tempest tests).
I'm going to recheck without proposed so see if I see the same problems.
