Once we do not kill keepalived for l3 agent, it might be usefull to override that. This is possible with neutron_l3_cleanup_on_shutdown When it set to True, keepalived will be restarted by l3 agent except first service restart, where it wil be killed by handler, since config should be loaded first.
