Meta-conditions for alert checkers

Hi Team,

We'd like to be able to create a kind of "meta" alert checker that combines the results of the "alert condition" checks across all associated entities within the alert checker before triggering an alert to fire. 

The use case for this is for multi-chassis bundles and pseudowire head-end, where a single "service" that we care about could have a variety of different paths or termination points in the network, but we only want to alert if some combination of entities is down. 

For example, given the following alert checker with these two entities (ports) associated:

We'd like to not have each individual entity alert separately, but only alert if the combination of both entities is down at the same time.

Let me know if you want further details and whether you think this is viable for implementation or not.

Best regards,

Matt Clancy
