The find_resource method had two hacks in in to support cinder
and keystone and I have removed those in favor of a monkey patch
for cinder.
The find_resource method used to attempt to UUID parse the id, but
it would do a manager.get anyway. I changed it to skip the UUID
parsing. This will make things run minorly faster and it supports
LDAP for keystone.
The find_resource used to attempt to use display_name=name_or_id
when finding. This was a hack for cinder support, but it breaks
keystone because keystone totally messes up with the bogus filter
and keystone refuses to fix it.
