Add the module name to the repr string so we can better identify
the resource that created the string. This is also convenient
for recreating the object from a string such as:
python examples/get.py openstack/compute/v2/server.py --data "openstack.compute.v2.server.Server(attrs={u'id': u'85d8ecf3-3757-43fd-b7a2-eb6636f7af1c', u'name': u'jenkins'}, loaded=True)"
