Yian Zong 03ac369854 Dell PowerMax: Fix SnapVx unlink failure
Dell PowerMax SnapVx unlink fails as the linked device
is not yet fully defined.
This patch fixed the issue by checking the new configuration
'snapvx_unlink_symforce' and the linked device 'defined' status
to determine the value of 'symforce' in the payload of
SnapVx unlink restcall.

Dell PowerMax Driver `Bug #2045230
<https://bugs.launchpad.net/cinder/+bug/2045230>`_: Fixed
the issue that Dell PowerMax SnapVx link fails as the linked device is not
yet fully defined.
Previously, the below operations could fail if the linked device was not
yet fully defined at the time of the call.
Now, when ``snapvx_unlink_symforce`` is enabled, those operations are not
interrupted by not fully defined devices.
By default, ``snapvx_unlink_symforce`` is ``False``. Use extreme caution
with this option. If used when a link is copy in progress or when a restore
is restore in progress, this will cause an incomplete copy and data on the
copy target would not be usable.
Impacted operations:
* Clone a volume
* Create a volume from a snapshot
* Create volume snapshots
* Delete volume snapshots
* Revert volume to snapshot
* Create generic volume group from source
* Unmanage volumes

Dell PowerMax Driver: introduced a new configuration option,
``snapvx_unlink_symforce``, to address Bug #2045230. See the Bug Fixes
section for details.
