To clean up stale ztunnels

	we may need to ztunnel to send its (uid, bootid / boot time) to us
	so that we can remove stale entries when the ztunnel pod is deleted
	or when the ztunnel pod is restarted in the same pod (remove old entries when the same uid connects again, but with different boot id?)

  istioctl dashboard proxy productpage-123-456.default

  # Open envoy admin dashboard for one pod under a deployment
  istioctl dashboard proxy deployment/productpage-v1

  # Open dashboard for the ztunnel-bwh89.istio-system pod
  istioctl dashboard proxy ztunnel-bwh89.istio-system

  # Open dashboard for a waypoint pod

- one end of the socket is in the application pod
- and the other end is in ztunnel's pod

and setting up iptables rules to funnel traffic thru that socket "tube" to ztunnel and back.

This effectively behaves like ztunnel is an in-pod sidecar, without actually requiring the injection of ztunnel as a sidecar into the pod manifest, or mutatating the application pod in any way.
