Is your feature request related to a problem? Please describe.
We have strict compliance requirements that mandate all E2E communications to services should be done over HTTPS. This includes metrics endpoints.

Describe the solution you'd like
I would like to request the addition of TLS support for the metrics server. Currently, there is no mention of HTTPS support in the documentation, and upon reviewing the code, I did not find any indication of TLS support for the /metrics route.

Describe alternatives you've considered
Haven't been able to come up with anything unfortunately. Putting a proxy to handle the TLS negotiation to /metrics wouldn't be a viable alternative since we require E2E TLS.
