Only notify handlers in service-check-containers

Notification of handlers on service config change is now
mostly delegated to the service-check-containers role,
but handlers that restart nova_libvirt and ovn_sb_db_relays
still remain.

Remove these remaining handlers to ensure that all service
containers are restarted by service-check-containers.
