[Calico CNI plugin](https://github.com/projectcalico/cni-plugin).

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:

	"k8s.io/apimachinery/pkg/types"
	gateway "sigs.k8s.io/gateway-api/apis/v1"
	"sigs.k8s.io/yaml"

	"istio.io/api/label"

)

      # ingressgateway services when pods in each cluster cannot directly
      # talk to one another. All clusters should be using Istio mTLS and must
      # have a shared root CA for this model to work.
      enabled: false
      # Should be set to the name of the cluster this installation will run in. This is required for sidecar injection
      # to properly label proxies

This is composed of two controllers - one driven from core Kubernetes types ("Kube Controller") and one by Istio types ("ServiceEntry controller").
