As Ztunnel operates at L4, we only have the destination IP/port (recovered via `SO_ORIGINAL_DST`).
This may be an IP of a Service, a Pod, or something outside the cluster.
Ztunnel will look up the destination from the [addresses](#address-type) it is configured with.

For traffic to unknown addresses, or to workloads that are not a part of the mesh, the traffic will just be passed through as is.

    - periodically copy the K8S JWT token for istio-cni on the host to connect to K8S.
    - injects the CNI plugin config to the CNI config file
        - CNI installer will try to look for the config file under the mounted CNI net dir based on file name extensions (`.conf`, `.conflist`)
        - the file name can be explicitly set by `CNI_CONF_NAME` env var

	if nil != p.Take(string(pod.UID)) {

		t.Fatalf("Expected nil Netns for the same uid twice")
