The operator uses the [IstioOperator API](https://github.com/istio/api/blob/master/operator/v1alpha1/operator.proto), which has
three main components:

- [MeshConfig](https://github.com/istio/api/blob/master/mesh/v1alpha1/config.proto) for runtime config consumed directly by Istio
control plane components.
- [Component configuration API](https://github.com/istio/api/blob/00671adacbea20f941cb20cce021bc63cbad1840/operator/v1alpha1/operator.proto#L42-L93), for managing

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)
    - If excluded, ignore the pod and return prevResult
1. Setup redirect rules for the pods:
    - Get the port list from pods definition, as well as annotations.

This is consumed in two ways:
* Some components just block on `watcher.WaitForCRD(...)` before doing the work they need.
