Rework zuul start/stop/restart playbooks for docker

If we need to start and stop, it's best to use playbooks.

We already have tasks files with start commands in each role,
so put the stop commands into similar task files.

Make the restart playbook import_playbook the stop and start
playbooks to reduce divergence.

Use the graceful shutdown pattern from the gerrit docker-compose
to stop the zuul scheduler.
