rest-server/daemon: use sd_notify_barrier for service reloading

Browse Source 
until now, we manually polled the systemd service state during a reload
so that the sd_notify messages get processed in the correct order
(RELOAD(old) -> MAINPID(old) -> READY(new))

with systemd >= 246 there is now 'sd_notify_barrier' which
blocks until systemd processed all prior messages

with that change, the daemon does not need to know the service name anymore
