IMO, the 'migrate_volume_completion' process in cinder should be fixed.

Title:
Cinder volume stuck in swap_volume
Status in Cinder:
In Progress
Status in OpenStack Compute (Nova):
In Progress
Bug description:
Cinder volumes are stuck in 'attaching'/'detaching' state when 'swap
volume' is executed.
A cinder volume is attached to a VM instance.
Then the cinder volume is swapped for a new volume by 'swap volume'.
Concretely the following API is called.
PUT /v2/{tenant_id}/servers/{server_id}/os-
volume_attachments/{attachment_id}
After the API is called, the attached volume(old volume) becomes stuck in
'detaching' state
and the new volume becomes stuck in 'attaching' state.
[How to reproduce]
