Generate envoy virtual host entry for pod IP and port about pilot HOT 5 CLOSED

Is it important to support pod IPs directly? There's a lot more churn in the pod registry, to the point we add this now, Envoy will be constantly restarting.

Or is this just for inbound connection?

Its inbound.. from an ingress controller. Just to be able to match the pod's local IP, when its present in the host field.
I don't think we need to restart at all.

I'm hitting this as well when testing the envoy-based ingress controller in #71.

I'm assigning this to myself as I plan to work on it on Sunday (yes it's a working day in here...).
If anyone else wanna give it a go before, that's fine too.

Oh, I didn't notice this is already assigned to @kyessenov. So, if you don't get the time to work it and want me to roll it next week, let me know.
