This came up in a Vancouver summit session (the python3 one I think). General
consensus there seemed to be that we should have grenade jobs that run python2
on the old side and python3 on the new side and test the update from one to
another through a release that way. Additionally there was thought that the
nova partial job (and similar grenade jobs) could hold the non upgraded node on
python2 and that would talk to a python3 control plane.
I haven't seen or heard of anyone working on this yet though.

IIRC, we also talked about not supporting multiple versions of
python on a given node, so all of the services on a node would need
to be upgraded together.
As I understand it, the various services talk to each other using
over-the-wire protocols. Assuming this is correct, why would we need to
ensure they are using the same python version?
