    [FLINK-3554] [streaming] Emit a MAX Watermark after finite sources finished

    Finite sources now emit a MAX_LONG watermark once they cleanly finished.
    
    This prevents loss of pending windows over finite sources when they finish.
    
    Canceling and stopping sources will NOT emit a MAX Watermark.
