Reason: Yep. The consensus was that cellsv1 work, including getting a cells+neutron job running, is taking momentum from v2.

Review: https://review.openstack.org/215459
Reason: I think we agreed in a nova meeting awhile ago that we're no longer adding feature support to cells v1, it's also in the devref now:

With cells v2 we aren't adding API feature parity for cells v1 so marking this as won't fix.
