Greg,

you're right in everything you said.

This was fixed in master in https://review.openstack.org/#/c/387993/ with
intent to fix tests and unblock the gate. But since those tests were
introduced in Ocata the fix was not backported to Newton.
So I've just did a partial packport of the root cause fix. Here it is:

Sincerely yours,
