[Feature Request] Implement a health-check endpoint.

[Jas-SinghFSU]

Not specific to my use-case but in general, having an endpoint that emits a health-check would be useful.

My specific use-case requires me to authenticate first by using an Identity Provider (Authentik) before I can access any web application. Since this IDP sits in the Reverse Proxy for my application, it's impossible to do a simple 200 status code check; because by default a 301 redirect is returned which redirects to authenticate via my provider.

Having the ability add an authentication exception in Authentik to a url such as https://mydomain.com/status/health would be extremely useful for being able to integrate this web-application into health-checkers.
