Scott's nova patch to support cinder v3 is dependent on a
python-cinderclient change for version discovery for min/max versions in
the v3 API. Once that's released we just bump the minimum required
cinderclient in global-requirements for pike and we should be good to go
But overall yeah I like the idea of just defaulting to cinderv3 in Pike,
as long as we can still get cinderv2 coverage in CI in master, which I
think we can do via grenade jobs.
