### Selection API

- plugin config "exclude namespaces" applies first
- ambient is enabled if:
    - namespace label "istio.io/dataplane-mode" == "ambient", and/or pod label "istio.io/dataplane-mode" == "ambient"
    - "sidecar.istio.io/status" annotation is not present on the pod (created by injection of sidecar)
    - pod label "istio.io/dataplane-mode" is not "none"
- sidecar interception is enabled if:

	// wait for an update events
	// total 3 update at before unlabel point: 1. init ns reconcile 2. ns label reconcile 3. pod annotation update
	mt.Assert(EventTotals.Name(), map[string]string{"type": "update"}, monitortest.AtLeast(4))
