Flavio Percoco 9352bb600f Enable pooling in devstack
This patch enables pooling by default. Pooling has become a central
piece for Zaqar, therefore, we ought to test on it always.

The patch also changes the behavior for pools in Zaqar. That is,
whenever a default pool is not found and a `message_store` section has
been configured, such section will be used as the default store. No
pools will be created out of this configurations so that users can still
configure their default store using zaqarclient.
