We decided we did not need to raise the minimum version of oslo.db allowed in kilo, because the old versions of the library do work, if they are installed from packages and not through setuptools.

After spending several hours exploring a bunch of options to make this actually work, some of which require making changes to test job definitions, grenade, or other long-term changes, I’m proposing a new approach:

1. Undo the change in master that broke the compatibility with versions of SQLAlchemy by making master match juno: https://review.openstack.org/141927
2. Update oslo.db after ^^ lands.
3. Tag oslo.db 1.4.0 with a set of requirements compatible with Juno.
4. Change the requirements in stable/juno to skip oslo.db 1.1, 1.2, and 1.3.

I’ll proceed with that plan tomorrow morning (~15 hours from now) unless someone points out why that won’t work in the mean time.
