The API is extended for generation of the NFS CSIDriver object. The YAML file under deploy/ was created by `yamlgen`. The contents of the csidriver.yaml file is heavily based on the upstream CSIDriver from the Kubernetes csi-driver-nfs project. Because ./tools/yamlgen uses the API, it gets copied under vendor/ . This causes two copies of the API to be included in the repository, but that can not be prevented, it seems.
