Simon Dodsley cd3a12006b [Pure Storage] Add volume group support
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.

[Pure Storage] Volume Group support added through new vendor-specific volume type
extra-specs. Volume Groups can be used to isolate tenant volumes into their own area
in a FlashArray, and this volume group can have tenant-wide storage QoS for the
volume group. Full replication support is also available for volumes in volume groups
and exisitng volume group volumes (such as VMware vVols) can be managed directly.
