cloud-image-utils needs to be installed

[Ian Booth]

For lxc image caching to work, cloud-image-utils needs to be installed on the bootstrap node. However, this had to be removed for a brief time because of packaging issues with precise. These now have been fixed, and so it's time to add the apt install of cloud-image-utils back again.

Without this package, starting lxc images fails, see http://paste.ubuntu.com/10302530/

Unfortunately, this also reintroduces the issue in bug 1407699 for precise on master. See http://juju-ci.vapour.ws:8080/job/joyent-deploy-precise-amd64/1531/ for example - the trusty machine 0 comes up, but the other 2 precise machines fail with cloud-init errors after its package gets removed by cloud-image-utils. I wonder if we could keep the removed packages: cloud-init cloud-initramfs-growroot cloud-utils in precise explicitly somehow, e.g. by installing them along with cloud-image-utils (should work for trusty as well).

A fix is ready to commit to trunk (already fixed in 1.22). But truck was blocked so it will land when trunk is open again.

Cheers, as trunk is unblocked now, I've re-added your fix to the queue.
