    cinder: accommodate v1 cinder client in detach call
    
    Call Cinder client's detach() with attachment_uuid only if the client
    is v2.
    
    Cinder client v2 supports passing volume_id and optionally
    attachment_id to its volume manager's detach() method, but v1 does
    not, only accepting volume_id.  Change I3cdc4992 indiscriminately
    passes both volume_id and attachment_id to the Cinder client
    regardless of its version, prompting with v1:
    
        TypeError: detach() takes exactly 2 arguments (3 given)

Title:
  cinder volume driver's detach() causes TypeError exception on v1
  cinder client

Status in OpenStack Compute (nova):
  Fix Released
Status in nova package in Ubuntu:
  New

Bug description:
  Nova version: git master branch's HEAD (as of today)
  Expected behavior: cinderclient v1 detach() called with accepted argument
  Actual behavior: cinderclient v1 detach() called with too many arguments

  Change I3cdc4992 indiscriminately passes both volume_id and
  attachment_id to the Cinder client regardless of its version even
  though Cinder client v2 supports passing volume_id and optionally
  attachment_id to its volume manager's detach() method, but v1 does
  not, only accepting volume_id.

  Calling Cinder client v1 detach() with both volume_id and
  attachment_id results in "TypeError: detach() takes exactly 2
  arguments (3 given)"

  Full traceback and proposed bug fix to follow.
