Press CTRL+C and A to abort playbook execution. You may
continue by pressing ENTER but the playbook will stop
executing after this system has been restarted and services
must be verified manually. To only restart services, set
openshift_master_rolling_restart_mode=services in host
inventory and relaunch the playbook.
