F18 cloud-init proposed update to 0.7.2

[Steven Hardy]

Hi all,

I've built and lightly tested a proposed update to cloud-init, which aligns
us with the recently released upstream 0.7.2 cloud-init release.

This includes all of the Fedora-related fixes mentioned in my justification
for the cloud-init-0.7.2-0.1.bzr809 update, but aligns us with the upstream
release, which includes a few additional fixes.

See:

Thanks!
