WIP

1. We should document the allow-list which is used by default (link to stolostron)
and that it can not be modified, this is customer question

"Hi team, IHAC asking will ACM observability gather all metric from managed cluster's prometheus? If not, is there a metric list for observability's default metrics?Error (if applicable)

"I've checked the ACM document but only see metrics type there. https://docs.redhat.com/en/documentation/red_hat_advanced_cluster_management_for_kubernetes/2.12/html-single/observability/index#metric-types "

2.

We should change a bit how we document custom-allowlist (we document that you can remove values, but maybe better add/remove)

What are default metrics in custom-allow-list?  Can you add and remove again?
https://docs.redhat.com/en/documentation/red_hat_advanced_cluster_management_for_kubernetes/2.12/html/observability/observing-environments-intro#removing-default-metrics

3. We should make a bit clearer difference between custom-allowlist (Platform metrics) and user-workload-monitoring metrics
