Add stub files to all services that don't currently have checks.

Behavior of stop playbook is very similar to the destroy
playbook.  This is meant when you may just want to bring down
the service for some sort of maintenance but not destroy all
the associated data. Also added support for the new playbook
into the kolla-ansible command.
