Moving cronjobs in beat.web to systemd

I get repeated e-mails every day concerning our BEAT jobs in beat.web. After more than a year, these scripts are pretty stable and it would be nice if we managed to make them not report unless there is a problem (exit status != 0).

In our internal webserver, I managed to implement this using systemd (report on failure only).

Could we do the same here? That would avoid the continuous torrent of "successful run" e-mails.
