* Allow limiting maximum number of alerts in webhook The webhook notifier is the only notifier that does not allow templating on the Alertmanager side. Users who encounter occasional alert storms (10ks of alerts going off at once for the same group) have reported webhook receiver systems not being able to cope with the load caused by the resulting large webhook notifier messages (the alerting rules also contained large annotations that can't be stripped away due to lack of templating). Reducing group size also wasn't an option, but this change proposes to allow truncating the list of alerts sent in the webhook body to a provided maximum length. This assumes that e.g. if a group receives 20k alerts, you really are fine only receiving 10k because you wouldn't be able to check them all anyway.
