e2e: add -nfs-driver=... option to select provisioner

When testing NFS-provisioning on a cluster that has an NFS-provisioner
and node-plugins deployed with a different driver-name, it is very
useful to have a commandline option to change the name of the
provisioner that is placed in the StorageClass.
