Subject: atomic-openshift: install as a system container

Use use_system_containers=true in the inventory file

alternatively you can select each component as:

use_openvswitch_system_container=true
use_node_system_container=true
use_master_system_container=true

system_images_registry holds the registry from where to fetch system
containers.
