2) `istio-cni` chart installs the CNI plugin. This should be installed after the `base` chart and prior to `istiod` chart. Need to add `--set pilot.cni.enabled=true` to the `istiod` install to enable its usage.

```console
helm install istio-cni -n kube-system manifests/charts/istio-cni --set profile=openshift
```

3) `istio-control/istio-discovery` chart installs a revision of istiod.
