Merge lp:~jtv/maas/pkg-1055523-cluster-uuid into lp:~maas-maintainers/maas/packaging

[Jeroen T. Vermeulen]

Set CLUSTER_UUID in the local celery config during cluster postinst.

As discussed with Julian and Raphael. This needs to accompany my trunk branch for bug 1055523. It will probably conflict with Julian's ongoing re-packaging work.

I've patched my current WIP branch with this change.
