Add silent_fatal
This PR adds a new function for use in cronscripts: silent_fatal
.
This function can be used to immediately halt the execution of a cron without sending mail to ESCALATE_MAILTO
. Of course, mail is still sent when the same cronscript calls non-fatal functions that increase the counters (warning or error) before silent_fatal
.
Aside from not sending mail to ESCALATE_MAILTO
, the behaviour is the same as that of a normal fatal
call.
