backend agnostic reconciliation test

[jayunit100]

we'd like something like https://github.com/kubernetes/kubernetes/blob/master/test/e2e/network/kube_proxy.go that we can use to run a/b comparisons in service of #325

@astoycos is interested in this, seems like a simple way to do it would be

make a service
for node in nodes:
   add 100 pods to the service

and then, say 1000 times

• modify pod count (scale up or scale down)

make 1000 go funcs:
  in parallel poll  the SEP until EACH ENDPOINT is obtained.

continuously.

how far is that from https://github.com/kubernetes-sigs/kpng/blob/master/server/cmd/kpng-backend-torture/main.go ?
