Description of problem: 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.
