Docker role refactor

- refactors the docker role to push generic config into docker role and wrap
  openshift specific variables into an openshift_docker role and it's
  dependent openshift_docker_facts role
- adds support for setting --confirm-def-push flag (Resolves
  https://github.com/openshift/openshift-ansible/issues/1014)
- moves docker related facts from common/node roles to a new docker role
- renames cli_docker_* role varialbes to openshift_docker-* (maintaining
  backward compatibility)
- update role dependencies to pull in openshift_docker conditionally based on
  is_containerized
- remove playbooks/common/openshift-docker since the docker role is now
  conditionally included
