F18 cloud-init proposed rebase update

[Pádraig Brady]

FYI, I broke your change into 2 and redid the tarball to exclude the large .bzr subdir

BTW I linked to the upstream source with a trick to reference the correct tarball:
  http://bazaar.launchpad.net/~cloud-init-dev/cloud-init/trunk/tarball/809

Built for rawhide, f18, f19:
  http://kojipkgs.fedoraproject.org/packages/cloud-init/0.7.2/
Note el6 is still at 0.6.3-0.12.bzr532

Submitted updates for f18, f19, where testers can add karma:
