Update etcd-backed Docker Swarm environment with Ubuntu and Photon. Switch from shell provisioning to Ansible. Update Vagrantfile to use new techniques pioneered in other environments. Switch away from meta-data/user-data for Photon customization, use Ansible instead. Signed-off-by: Scott S. Lowe <scott.lowe@scottlowe.org>
