Add /healthz endpoint to server #259

Open ItalyPaleAle opened 8 months ago

This PR adds a tiny handler for /healthz, which responds with an empty response and 204 status code. This is very helpful to set up healthchecks (for example, liveness probes), in a container orchestrator or proxy.

I saw that 2 years ago, someone started working on health endpoints in #159, but that PR seems to have been abandoned.

This PR is a lot simpler in the approach as it always responds with a 204 status code, without performing any actual check: it just asserts that rest-server is running and healthy.
