Support multi nova cell v2

Registered by Joshua Harlow on 2017-01-10

Nova offers cells as a scale-out concept.

Kolla does not currently understand nova-cells; so therefore it can not understand the nova scale-out concept.

For operators that use kolla and use nova-cells this makes it hard to use kolla; that is bad.
