I don't think we need the param --skip-cni-install, it will let the user confused.

You can install the cluster using the kubekey config that sets up the .spec.networks.plugin as none and sets up addons to deploy your CNI plugin.

For example, the following is a kubekey config example:

network:
    plugin: none
addons:
  - name: calico
    namespace: kube-system
    sources: 
      yaml: 
        path: 
        - /mycluster/calico/calico.yaml

i mean kubecni，not network plugin. because containerd already provide cri-containerd-cni-1.6.0-linux-amd64.tar.gz option, so i think, if i am using containerd as cri. there is no longer need kubecni.
