- Read PV's AZ info from fault-domain label of the PV object for snapshotting. - Store PV's AZ info in the VolumeInfo. - Add tests for reading the label from the PV object. - Remove availability zone validation in AWS and GCP BlockStorageAdaptor. - Add volumeAZ as a parameter to methods in the BlockStorageAdapter interface. - Get AZ from VolumeInfo when restoring PV snapshot. - Remove references to PV availability zone in docs.
