Public bug reported:
When the nova volume API makes calls into the Cinder API using
cinderclient, if cinder raises an exception like Forbidden or OverLimit,
the nova volume api does not catch these exceptions. So they go up to
the nova rest api, resulting in a 500 to be returned.
Here's an example from a tempest test:
Traceback (most recent call last):
File "/home/ubuntu/tempest/tempest/api/compute/volumes/test_volumes_get.py",
line 51, in test_volume_create_get_delete
metadata=metadata)['volume']

line 55, in create_volume
resp, body = self.post('os-volumes', post_body)

tempest.lib.exceptions.ServerFault: Got server fault
Details: Unexpected API Error. Please report this at

<class 'cinderclient.exceptions.Forbidden'>
The volume API needs to wrap these exceptions and return the nova
equivalent to the rest API so the appropriate return code can be
returned.
