Description

Title: Export process_start_time_seconds Prometheus metric

Description:

When querying the /stats/prometheus endpoint on the admin page, it would be immensely helpful to add process_start_time_seconds. This metric is typically a gauge reporting the seconds since January 1 1970 when the process started, and is commonly used by prometheus consumers to track cumulative metrics (notably by prometheus-to-sd).

(I'd be glad to take a crack at adding this :))
