Keeper Improvement: Send Only Keeper Metrics/Events for Prometheus

Why it matters

This feature restricts the Prometheus metrics and events to only those related to Keeper, reducing noise and improving monitoring focus specifically on Keeper components. It helps users monitor Keeper performance and behavior more efficiently without unrelated metrics cluttering the data.

How to use it

No explicit user action is required aside from enabling Prometheus metrics collection for Keeper components. The system now automatically filters and sends only Keeper relevant metrics/events to Prometheus.
