Merge pull request #5995 from ashcrow/docker-gc-daemonset

Automatic merge from submit-queue.

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 ``docker_gc`` daemonset will be created along with adding a ``docker-gc``
sa.
