https://launchpad.net/bugs/1341619

* New upstream bugfix release:
  - Auto-link node MACs to Networks (LP: #1341619)

[ Julian Edwards ]
* debian/maas-region-controller.postinst: Don't restart RabbitMQ on
  upgrades, just ensure it's running.  Should prevent a race with the
  cluster celery restarting.
* debian/rules: Pull upstream branch from the right place.

[ Andres Rodriguez ]
* debian/maas-region-controller.postinst: Ensure cluster celery is
  started if it also runs on the region.
