Dell PowerMax Snapvx unlink fails

[Yian Zong]

Dell PowerMax SnapVx unlink fails as the linked Device is not yet fully defined.

The proposed fix for U4P 9.2 and above is:

Add a new Boolean configuration 'snapvx_unlink_symforce' in cinder.conf

If the option snapvx_unlink_symforce is True
Get the status of the defined state presented by the REST API interface
If the DEFINED state is False, then proceed with an unlink –symforce operation
If the DEFINED state is True, proceed as usual

If the option snapvx_unlink_symforce is False or MISSING
If the DEFINED state is False, raise an exception and proceed as usual
If the DEFINED state is True, proceed as usual

    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.
