Fix volume id conversion in nova-manage volume
Fix volume id conversion in nova-manage volume

  The nova-manage volume commands weren't updated when the switch
  from int volume-id's to uuid's was made.  This updates the
  param2id method to call the appropriate conversion, and doesn't
  attempt to cast the value to an int.

  There is an additional issue with the nova-manage commands with the
  introduction of Cinder.  The calls in nova-manage are direct to the
  nova database which when using Cinder is not valid.  Add an error message
  when trying to use delete or re-attach commands as they don't work.

  This change deprecates the nova-manage delete function as it's now
  implemented as an admin extension (nova commit id: If795599d and
  cinder commit id: I29f4b892).

  The reattach command is only valid for nova-volumes, a similar extension
  will need to be added to cover cinder at which time the nova-manage volume
  reattach can be deprecated as well.

  Partial fix for bug #1051603
