Fix a problem in creating consistency group in ProphetStor driver.

a.Failed to create CG in the storage:
  Storage site cannot accept CG uuid including "-" word. Before
  sending API to back-end storage, the "-" word in the CG uuid
  needs to be removed.
b.Failed to delete volume of CG:
  Corrected api leaving group operation key.
