Make nfs version for nova ephemeral storage configurable

New parameter ``NovaNfsVersion`` allow configuring the NFS version
used for nova storage (when NovaNfsEnabled is true). Since NFSv3
does not support full locking a NFSv4 version need to be used. To
not break current installations the default is the previous hard
coded version 4.
