Support HTTPS_PROXY env variable

[geoberle]

I would really love to see some option to let kube-oidc-proxy know that it should use a specific HTTP proxy for communication with the upstream Kubernetes API.

I tried the usual HTTP_PROXY and https_proxy ENV variables but without success. Is there a way i'm not aware of?

Thanks for looking into this.
