Goutham Pacha Ravi a75fe3d7cc Allow configuration of a back end specific availability zone ... "storage_availability_zone" in the [DEFAULT] section of manila's configuration file has allowed deployers to configure and manage both service (scheduler, share manager) and storage system availability. However, quite often manila's services (api, scheduler, share and data managers) are run on a dedicated control plane that is a different failure domain from that of the storage that manila manages. Also, when using share replication, deployers would need to run multiple manila share manager services with different configuration files, each with their own "storage_availability_zone". To allow flexibility of separating service and storage availability zones, we introduce a new configuration option "backend_availability_zone" within the share driver/backend section. When this option is used, it will override the value of the "storage_availability_zone" from the [DEFAULT] section.
