Agreed. I'd also like to see other project migrated before pulling
oslo.db out from oslo-incubator

I'd also add that pulling oslo db into its own package means that
projects using Oslo's db code have to be migrated as well. I think
it's a bit late for that. The focus should be on making sure current
code is stable enough for the not-so-far release.

Thanks for the hard work!
