Title:
  Race condition in quickly attaching / deleting volumes

Status in Cinder:
  Confirmed
Status in OpenStack Compute (nova):
  Expired
Status in tempest:
  Invalid

Bug description:
  It seems that there is a race condition in the stress
  volume_attach_delete test. It creates VMs and volumes, attaches
  volumes and deletes everything.

  The test is waiting for volumes to be in 'in-use' state before
  deleting VMs. It seems that Nova/Cinder don't have time to register
  volumes as attached in their databases before VMs get deleted. Volumes
  are then left attached to deleted VMs and unable to be deleted.
