Add simple playbook task for upgrading servers

We want to treat our servers as cattle; hopefully when this is fleshed out a bit more, it can accomplish the job without too many casualties.

requested review from @jelle and @klausenbusk

Why should we reboot on every update?

Can't we put a when pacman task is changed at least?

Compare with previous version

if pacman_upgrade doesn't contain .changed for some reason, then pacman_upgrade.changed will fail, but the pacman_upgrade is changed test will succeed.

Good concept but needs documentation in the README and a suggestion on how often to run this.

Probably in a decent enough shape to merge before reiterating further. I have used it twice so far without any noticeable drawbacks.
