Aggregate alerts under a group

Hey Checkly team :wave:

Currently if we have multiple checks under a group and alerting is setup to be routed to tools like PagerDuty or OpsGenie, there are times where we'll be bombarded with alerts. This happens when the check dependencies all share the same downstream call, and that downstream call is problematic.

If its possible to aggregate the alerts by the group, this would drastically reduce the alerting noise if we get into another instance where all checks under a group starts to fail. I'm not sure if this is possible due to a limitation from OpsGenie, PagerDuty etc.

But the end goal would be to send a single alert that references the group, and additional metadata is added which specifies which check is failing, as opposed to each check being an individual alert.
