System container docker

This change allows for the use of either the traditional package install
of docker OR a system container install of docker.

Two new inventory options, openshift_docker_use_system_container and
openshift_docker_systemcontainer_image_registry_override, have been
added which are be used to install with a system container. By default
this option is commented out.

One new fact has been added:

- docker.service_name: docker by default, container-engine-docker
for system container
