- If excluded, ignore the pod and return prevResult
1. Setup redirect rules for the pods:
    - Get the port list from pods definition, as well as annotations.
    - Setup iptables with required port list: `nsenter --net=<k8s pod netns> /opt/cni/bin/istio-iptables ...`. Following conditions will prevent the redirect rules to be setup in the pods:

			metav1.PatchOptions{},
			// Both "pods" and "pods/status" can mutate the metadata. However, pods/status is lower privilege, so we use that instead.
			"status",
		)
	return err
