NFSD: Add a key for signing filehandles
A future patch will enable NFSD to sign filehandles by appending a Message
Authentication Code(MAC). To do this, NFSD requires a secret 128-bit key
that can persist across reboots. A persisted key allows the server to
accept filehandles after a restart. Enable NFSD to be configured with this
key via the netlink interface.
