The details for the deployment & installation of this plugin were pretty much lifted directly from the
[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:

    logLevel: debug

    # Configuration file to insert istio-cni plugin configuration
    # by default this will be the first file found in the cni-conf-dir
    # Example
    # cniConfFileName: 10-calico.conflist

    # CNI bin and conf dir override settings
    # defaults:
    cniBinDir: "" # Auto-detected based on version; defaults to /opt/cni/bin.
    cniConfDir: /etc/cni/net.d
    cniConfFileName: ""
