Epic Goal

Add an alert to identify clusters that are not reporting observability data,
which can indicate either an issue with the observability stack or the connection to the cluster.

This can be achieved by adding a metric that reports the list of clusters managed by ACM.
Then creating an alert that check for each cluster if it also reports the `watchdog` alert, that indicates the health of the cluster alerting.

Why is this important?

This will allow us to let the Admin know in a short period of time if there is an issue with getting data from a managed cluster.
It is a health check.

Scenarios

A cluster network is having issue  - An admin managing the cluster with ACM will be notified that the cluster has not reported data for the last X minutes.
