Remove wrong reload option
Hi!
Running systemctl reload prometheus-node-exporter.service
will stop the service, quitting with (from journalctl):
Aug 01 12:02:30 mymachine systemd[1]: prometheus-node-exporter.service: Deactivated successfully.
Aug 01 12:02:30 mymachine systemd[1]: prometheus-node-exporter.service: Consumed 15h 1min 22.042s CPU time, 35.7M memory peak, 0B memory swap peak.
It turns out that this service probably can't be reloaded like prometheus (I didn't investigate this though), and it most likely also does not need it, since it gets all of its config via env vars and those only get applied on restart anyways.
