Public bug reported:
Swap volume API can swap a in-use volume with available volume.
Therefore in-use volume should be available and available will be in-use.
In face, volumes will stay in detaching and attaching respectively after send
swap volume request to nova.
But those volumes had been swapped.
Following are commands flow.
