Pure Storage FlashArray's have a construct called a Volume Group within which volumes can be created. The volume group can have storage QoS levels assigned to it that limits the combined bandwidth and/or IOPs of all volumes within the volume group. Adding volume group support requires the use of vendor-specific volume type extra-specs which will allow a specific volume type to be limited to a volume group on a specified backend array. The volume group does not require QoS settings, but these can be applied using the vendor-specific volume type extra-specs. This patch provides the ability to create, manage and delete volume groups and to manage volumes in the volume group. Additonally, this patch will allow existing volumes in a volume group to be managed using the ``cinder manage`` command, including VVOLss that are in volume groups in non-replicated FlashArray pods. Retyping of volumes in and out of a volume group based volume type is also supported. Volume group based volumes can also be replicated as any other volume on a FlashArray and replication failover of these replicated volume group based volumes is also supported. Additional vendor-specific volume type extra specs are detailed in the updated driver documentation and in the release notes.
