The ambient CNI agent is the only place where ambient network config and pod redirection machinery happens.

A secondary goal was to enable a smoother on-ramp from "Zero" to "Getting some value".
Historically, Istio had to really be consumed all-or-nothing for things to work as expected.
In particular, an easy answer to "I just want to have mTLS everywhere, then I can think about adopting the rest of service mesh" was desired.

## Goals

Ztunnel should:

		// Existing pods will be handled by the dataplane using `GetAmbientPods`,
		// and the initial enqueueNamespace, and new pods will be handled by the CNI.

	case controllers.EventUpdate:
		// For update, we just need to handle opt outs
		newPod := event.New.(*corev1.Pod)
		oldPod := event.Old.(*corev1.Pod)
		ns := s.namespaces.Get(newPod.Namespace, "")
		if ns == nil {
			return fmt.Errorf("failed to find namespace %v", ns)

{{- /* Core defines the common configuration used by all webhook segments */}}
{{/* Copy just what we need to avoid expensive deepCopy */}}
