Description of the request :

 Based on the KB mentioned below recommended way to manage and notify users using deprecated APIs is not scalable in large environments and using CLI  `cluster-admin` privileges is required to view the deprecated API report.

The customer needs an efficient way to observe and report deprecated API usage by apps in different namespaces via PromQL which is currently not supported.

Customers want this information to be available via metrics that can be exported to dashboards and Alerting mechanisms.
