So that on a delete & recreate of the service the previous pv's still
point to this nfs-provisioner. We cannot use the hostname since the actual
host doesn't know how to resolve service addresses inside of the cluster.
To support this would require the installation of kube-dns and
modification to the /etc/resolve.conf file on each host.
