Specifically:

- The CNI installation script is containerized and deployed as a daemonset in k8s.  The relevant calico k8s manifests were used as the model for the istio-cni plugin's manifest:
    - [daemonset and configmap](https://docs.projectcalico.org/v3.2/getting-started/kubernetes/installation/hosted/calico.yaml) - search for the `calico-node` Daemonset and its `install-cni` container deployment

For consistency, the same profiles are used across each chart, even if they do not impact a given chart.

Explicitly set values have highest priority, then profile settings, then chart defaults.

As an implementation detail of profiles, the default values for the chart are all nested under `defaults`.
When configuring the chart, you should not include this.
