Sean McGinnis 7c1e92278c Add per-backend availability zones

When volume backends were defined in the [DEFAULT] cinder.conf config
section, it did not make sense to have more than one AZ config setting.
Now that we have multibackend and we have deprecated the ability to
configure backends in DEFAULT, we can set AZs per backend section.

This previously required setting up a separate service using a different
cinder.conf to have more than one AZ. But since the vast majority of
backends are separate physical devices, there is no reason to restrict
the control plane service to be on separate nodes to support separate AZ
configurations.

     Availability zones may now be configured per backend in a multi-backend
     configuration. Individual backend sections can now set the configuration
     option ``backend_availability_zone``. If set, this value will override
     the [DEFAULT] ``storage_availability_zone`` setting.
