Niels de Vos 87f87141be deploy: add CSIDriver for NFS
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.
