[Openstack] Remove Zones code - FFE

-1 for ServerGroup because in the OSAPI terminology Server is a guest instance rather than a physical host.

I assume that the relationship between zone and availability zone will still exist (and I remind you that host-aggregates have been coming along to). So you have:

?? <--> Availability Zones <--> Host Aggregates 

How about ?? == Deployment [Slice | Area | or Section]

I know that Region may not be liked by some people, but that is good too.
