    Add checks for volume status when rebuilding
    
    When rebuilding, we should only allow detaching
    the volume with 'in-use' status, volume in status
    such as 'retyping' should not allowed.

Title:
  Lack of volume status checks when detaching volume in rebuild.

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Currently, when rebuilding an instance with volume attached, the Nova
  compute manager will directly call _detach_volume() which will skip
  the checks of volume status (volume_api.check_detach) and setting the
  volume to 'detaching' (volume_api.begin_detaching) at Cinder side.
  This is different with the normal volume detach process.

  Besides, when rebuilding, we should only allow detaching the volume
  with in-use status, volume in status such as 'retyping' should not
  allowed.
