standalone: add support to build containers before deployment

* Create a new role, container-build, that will install
  a Docker registry in a container, running on port 5001
  and run tripleo_container_image_build to build TripleO images from
  scratch.
* Update the standalone deploy role so it can deploy TripleO from
  locally built container images and not from a remote registry.
