"""Test local delete in the API of a server with a volume attached.

This test creates a server, then shelve-offloads it, attaches a
|
|
volume, and then deletes the server.
|
|
|
|
Since the server is shelved-offloaded it does not have instance.host
|
|
set which should trigger a local delete flow in the API. During local
|
|
delete we should try to cleanup any attached volumes.
|
|
|
|
This test asserts that on a local delete we also detach any volumes
|

and destroy the related BlockDeviceMappings.
