Moved to tracking the 'docker-engine' package from the archives instead of lxc-docker
This release also has the benefit of moving from device-mapper backend storage (not recommended) to AUFS by default. This yields in faster performance, and reduced disk usage for container fs layers.
Includes a fix from Gennady to properly restart the docker daemon during networking changes and corrects the ordering of ansible handlers! Thanks Gennady!
Various project meta cleanup relating to testing and having greens in CI.
