Add docker composable service template

This uses a puppet-tripleo profile to configure and start docker
in step1 of the deployment, which is before we attempt to deploy
any containers (see docker/services/README.rst#docker-steps)

This enables existing environments on upgrade to configure things
correctly, without using the docker/firstboot/setup_docker_host.sh
- the firstboot approach may still be needed for atomic, but for
environments where we can run puppet on the host this integrates
more cleanly with our existing architecture I think.
