Comment 5 for bug 1693017

I have a fix here: https://review.openstack.org/#/c/467131/ for this bug. However, it needs two other charms.openstack changes to land, but this should happen shortly. I'll tag this bug in an updated review for the above change. However, each charm will need to be changed to call the mocking function, so this affects:

aodh, barbican, barbican-softhsm, designate, manila, manila-generic, tempest

and anything else that uses charms.openstack. Obviously, this doesn't affect build charms.
