This is something I wanted to dig into at the summit in fact, mostly
because I'm not sure I agree... Sure migrate is now an openstack
project, but so is olso and we're happy to use that. So I don't think
it being abandoned by the original author is a strong argument.

Its not clear to me what alembic gives us that we actually want...
Sure, we could have a non-linear stream of migrations, but we already
do a terrible job of having a simple linear stream. I don't think
adding complexity is going to make the world any better to be honest.

These are the kind of issues I wanted to discuss in the nova db summit
session if people are able to come to that.
