`CmdAdd` is triggered when there is a new pod created. This runs on the node, in a chain of CNI plugins - Istio is
run after the main CNI sets up the pod IP and networking.

1. Check k8s pod namespace against exclusion list (plugin config)
    - Config must exclude namespace that Istio control-plane is installed in (TODO: this may change, exclude at pod level is sufficient and we may want Istiod and other istio components to use ambient too)
