    nfsclient: Add a new nfs_client_rdma_enable variable
    
    This patch adds a new nfs_client_rdma_enable variable
    to /etc/rc.d/nfsclient to enable the client side of
    NFS over RDMA.  The client side of NFS over RDMA
    requires the nfsclrdma.ko module, which is still under
    test/review.
    
    I wanted to get the "glue" into main so that others
    could test the module more easily.  Avaliability of
    the module will be announced on freebsd-current@ soon.
    
    It should not affect non-RDMA operation.
    
    I've specified a long MFC, since the module still
    requires extensive testing and, hopefully, a review.
    
    MFC after:      3 months
