Description of problem: Future versions of Red Hat Enterprise Linux and OpenShift will ship exclusively with the open standards based CRI-O, Skopeo, Buildah and Podman. This will allow Red Hat to better serve customers with nimbler tooling that also has the great benefit of delivering more secure solutions. So far, Director has been using Docker to manage containers but the package won't be maintained anymore in the future, so we need to switch Director to use Podman. Condition of satisfaction: Docker isn't needed anywhere in TripleO and was replaced by Podman for the container lifecycle management on both the undercloud and overcloud.
