This patch adds a mirror for Ubuntu Cloud Archive. The releases
mirrored is selective, only covering the currently supported
Ubuntu and OpenStack versions.
Having this mirror available aids deployment projects which
consume these packages by ensuring that all apt packages needed
are available in mirror local to the nodepool cloud provider.
Note:
I have no real understanding of how puppet/system-config works
and don't know how to test this patch. If there's no
system-config gate check to validate that this works, please can
someone assist by testing and providing feedback.
