This proposed patch to drop the db downgrades in Nova master is making
Turbo Hipster face plant - https://review.openstack.org/#/c/175010/

It appears that turbo hipster is walking all the way up, then walking
back down through migrations, which clearly, is no longer a thing.

It would be nice to merge this patch sooner rather than later, so would
be great if Turbo hipster could function on migrations without
downgrades RSN.
