We are using an ingress hostname as the upstream of a prom-label-proxy. The ingress relies on the host header to route the traffic.
But currently, the proxy doesn't rewrite the host header. As a result, prom-label-proxy will send requests to the upstream with the host header proxy.local.example.com and it'll always get a 404 error since the ingress couldn't find a proper route for this hostname.
So we are here to request a feature flag that could rewrite the host header while proxy requests.
