Many tasks that use Docker have become specified already, but
not all. This change ensures all tasks that use the following
modules have become:
* kolla_docker
* kolla_ceph_keyring
* kolla_toolbox
* kolla_container_facts
It also adds become for 'command' tasks that use docker CLI.

Add a new subcommand 'check' to kolla-ansible, used to run the
smoke/sanity checks.
Add stub files to all services that don't currently have checks.
