Any code the Kolla team is building themselves should still support
Python 2 under the deprecation policy, but if all of the projects that
Kolla packages support Python 3, I'm not sure why we would also require
them to package Python 2 versions.
It might be necessary for them to use python 2 versions of some distro
packages for a while, I guess. But I don't see any utility in Kolla
offering its users a choice of which version of Python to use on a given
platform. I would just pick the highest version number that works.
Am I missing something? Maybe we need to clarify the guidelines?
