- watches k8s resource for existing pods, so that pods that have already been started can be moved in or out of the ambient mesh.
- sends UDS events to ztunnel via a socket whenever a pod is enabled for ambient mesh (whether from CNI plugin or node watcher), instructing ztunnel to create the "tube" socket.

This can be a `Service` or a `Workload`.

The address type has the following goals:
* It should support (but not require) on-demand lookups.
  * Specifically, ztunnel should be able to send a request to the control plane to answer "I got a request to send traffic to 1.1.1.1, what is 1.1.1.1?"

  // If unspecified, the rule defaults to a http catch-all. Whether that sends
  // just traffic matching the host to the default backend or all traffic to the
  // default backend, is left to the controller fulfilling the Ingress. Http is
  // currently the only supported IngressRuleValue.
