Consistency group configuration with Thin Image and GAD

Not all consistency group configurations are supported when sharing a Thin Image volume with a GAD volume.

Pairs in a Thin Image consistency group must be in the same storage system. Therefore, if a GAD P-VOL and S-VOL are each used in Thin Image pairs, the Thin Image pairs cannot be registered to the same consistency group.
