Following the recent Prometheus outage on the OSDF director, implementing a health check for the Prometheus server would be highly beneficial. Querying process_start_time_seconds should provide a simple way to verify if the server is responding with valid data.

Currently, the pelican_component_health_status metric tracks the health of various Pelican services using a component label. Adding a prometheus label value to this metric would be the most effective way to integrate Prometheus health monitoring.
