Title:
  Failed to detach volume because of volume not found error prevents vm
  teardown

Status in Cinder:
  In Progress
Status in OpenStack Compute (Nova):
  Confirmed
Status in Tempest:
  Fix Released

Bug description:
  When running the boto tests in the gate we get a periodic race on
  Cinder volumes that can be seen as follows:

  Attach the volume (vdh) - http://logs.openstack.org/29/84829/6/check
  /check-dg-tempest-dsvm-full-
  reexec/7e595ac/logs/screen-n-cpu.txt.gz?level=INFO#_2014-04-04_11_38_35_995

  Detach the volume (vdh) - http://logs.openstack.org/29/84829/6/check
  /check-dg-tempest-dsvm-full-
  reexec/7e595ac/logs/screen-n-cpu.txt.gz?level=INFO#_2014-04-04_11_38_41_477

  Stack trace horribly because the volume is not found -
  http://logs.openstack.org/29/84829/6/check/check-dg-tempest-dsvm-full-
  reexec/7e595ac/logs/screen-n-cpu.txt.gz?level=INFO#_2014-04-04_11_38_43_866

  Stack trace horribly because we try again? -
  http://logs.openstack.org/29/84829/6/check/check-dg-tempest-dsvm-full-
  reexec/7e595ac/logs/screen-n-cpu.txt.gz?level=INFO#_2014-04-04_11_42_29_353

  Because of this we end up with a volume in an undeletable state, and
  the tests fail in making it go away (it remains marked in-use even
  though the guest that was using it is gone) -
  http://logs.openstack.org/29/84829/6/check/check-dg-tempest-dsvm-full-
  reexec/7e595ac/console.html#_2014-04-04_11_42_47_940
