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.
