Is this an improvement to replace kubectl proxy-forward or it's also for test enhancement? Does the 8000 not reachable issues come from port-forward or not?

From what we have seen, kubectl port forwarding is not very stable. So instead, we use kind config to setup port forwarding. So far it looks like running fine. I am just running it one more time to confirm it is working.
