Description

Currently whisker-backend has no health check built into the application. It would be helpful to have whisker-backend check that it's health, perhaps even make a call to Goldmane and if it fails then fail the health check?

With a health check a k8s probe could be added to kick the pod when it becomes unhealthy.

Thanks

Contributor guide

Research direction
Examine the existing HTTP server setup in whisker backend. Add a '/health' endpoint that returns a simple status (200 OK). Optionally, enhance it to make a request to Goldmane and include that status. Look for patterns like the use of 'net/http' or a router. Ensure the health check can be used as a Kubernetes liveness or readiness probe.
