Support `connectionPool` and `loadBalancer` from Gateway to Backend

[machine3]

What would you like to be added: Support connectionPool and loadBalancer from Gateway to Backend. Just like Istio DestinationRule

apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
  name: my-destination-rule
spec:
  host: my-svc
  trafficPolicy: 
    connectionPool: <-- here
    loadBalancer:  <-- here
  subsets:
  - name: v1
    labels:
      version: v1
  - name: v2
    labels:
      version: v2
    trafficPolicy: 
      connectionPool: <-- here
      loadBalancer:  <-- here
  - name: v3
    labels:
      version: v3

Why this is needed:

I vote to change the title & description to support connectionPool and loadBalancer from Gateway to Backend

This is an interesting idea which would need to be proposed as a GEP.

/triage accepted /kind gep

However we're currently focused on getting our GA release completed (see milestone v1.0.0) and this would not seem to be something that would need to block the release, so we're not ready to prioritize this and we would ask that v1.0.0 milestone issues get priority so we can focus there, and come back to this after the release.
