openshift_hosted: Add docker-gc

Two new inventory variables have been created:

- openshift_crio_enable_docker_gc: Enable docker_gc daemon set
- openshift_crio_docker_gc_node_selector: Optional dictionary to use node
selector

When openshift_crio_enable_docker_gc and openshift_use_crio are both true
then dockergc daemonset will be created along with adding a dockergc
sa.
