Merge "Disable automatic system updates on Ubuntu"

Disable automatic system updates on Ubuntu

The cloud-init package has a hard dependency on the automatic update
mechanism in Ubuntu 14.04. As removing this causes systems to not be
accessible when booted, instead we're just going disable all of the
options for the automatic update system
