Update Cinder test that incorrectly handles 404

The volume test that checks the "volume:delete" action incorrectly
handles a 404. When a role doesn't have permission to delete a
volume, Cinder actually throws a 403 and not a 404.

This commit also refactors existing test to group basic volume CRUD
(create, read, update, and delete) tests into a single file.

Additionally, there was not a test for "volume:update", so this commit
also covers that action.
