Openshift Containernetworking cni plugins (supported/unsupported) DaemonSet yaml file

Note.md

1. In above yaml files, apiVersion is set to app/v1 as below, I copied it from Dan's PR which I think is used in openshift. With kubernetes, apiVersion is set to extensions/v1beta1

apiVersion: apps/v1

2. the image names in above files will be replaced by env vars set in network operator manifests; example can be found here: https://github.com/openshift/cluster-network-operator/pull/54/commits/4211d3a41cf0b9cd526a1229c08453f18038a7d9#diff-1cf3d8447bdd10b4fd172cc55ca05700R37

{{.ContainerNetworkingCNIPluginsSupportedImage}} and {{.ContainerNetworkingCNIPluginsUnsupportedImage}}

3. Tomo helped to provide the correct format of command and arg, espically how * shall be used in pod spec args:

    command: ["/bin/sh"]
    args: ["-c", "cp -rf /usr/src/plugins/bin/* /host/opt/cni/bin"]
