Missing an "http auth free" health endpoint

[KrustyHack]

Hi,

It would be nice to have a health endpoint at path / which is exposed without http auth even if we use http auth.

For now I can't use my chartmuseum Helm charts with http auth in my Kubernetes cluster with a GCE Ingress because healthcheck fail indefinitely. :/

Makes sense to me. I'd be willing to add this, if the maintainers think this is a good idea?
