Custom metrics server for Semaphore

This project exposes an external metrics provider to fetch Semaphore metrics. It's built upon custom-metrics-apiserver. The metrics exposed by this server can be used when configuring a Kubernetes HorizontalPodAutoscaler to scale a Semaphore agent pool.

Check the Semaphore agent Helm chart for usage.
