[openstack-dev] no-downtime DB migrations

Having database migrations between commits is necessary to be able to run
openstack components in a continuous deployment environment, so I'm really
excited about this. I bet the Rackspace guys are as well.
I believe we're defining policy here, so there isn't a lot of technical work to
be done. If there is please let me know, I'm happy to chip in where ever
necessary.
I agree with the constraints Robert laid out. We need to make sure each core
reviewer enforces them during the review process.
I've seen that Grenade (https://wiki.openstack.org/wiki/Grenade) is "a test
harness to exercise the OpenStack upgrade process between releases."
Perhaps the
work needed to be done here is to get a grenade commit gate up that ensures that
a commit successfully upgrades the database between commits (I'm assuming that
doesn't already exist).

The glance meeting is in a couple of hours. I didn't see database migrations on
the agenda. Mark, can it be added?
Thanks!
