    rdma : agregate a vectored read as one
    
            Back port of : http://review.gluster.org/9321
    
    For a vectored read with payload count>1 will make two read
    requests and to hold that a single contiguous memory is allocated.
    So after completing the read request, instead of sending as vector
    we will aggregate all the reads one.

    rdma: post multiple work request in a single call.
    
            Back port of : http://review.gluster.org/9327
    
    ibv_post-send will allow to send multiple work request
    in a single call posting as linked list.
    
    So if the payload count > 1, we can perform the data
    operation in a single call to ibv_post_send.

    rdma:read multiple wr from cq and ack them in one call
    
            Back port of : http://review.gluster.org/9329
    
    we are reading one work completion request at a time
    from cq, though we can read multiple work completion
    requests from cq. Also we can acknowledge them in
    one call itself. Both will give a better performance
    because of less mutual exclusion locks are being performed.

    rdma: pre-register iobuf_pool with rdma devices.
    
            Back port pf : http://review.gluster.org/9506
    
    registring buffers with rdma device is a time consuming
    operation. So performing registration in code path will
    decrease the performance.
    Using a pre registered memory will give a bettor performance,
    ie, register iobuf_pool during rdma initialization. For
    dynamically created arena, we can register with all the
    device.
