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:

* Configurable etcd quota backend bytes in GCE ([#59259](https://github.com/kubernetes/kubernetes/pull/59259), [@wojtek-t](https://github.com/wojtek-t))
* Updates Calico version to v2.6.7 (Fixed a bug where Felix would crash when parsing a NetworkPolicy with a named port. See https://github.com/projectcalico/calico/releases/tag/v2.6.7) ([#59130](https://github.com/kubernetes/kubernetes/pull/59130), [@caseydavenport](https://github.com/caseydavenport))

* The calico-node addon tolerates all NoExecute and NoSchedule taints by default. So Calico components can even be scheduled on tainted nodes. ([#57122](https://github.com/kubernetes/kubernetes/pull/57122), [@caseydavenport](https://github.com/caseydavenport))
