    [TRAFODION-3175] enhance ExeCliInterface get interface to return null 
indicator

    enhance the ExeCliInterface get method to return NULL ptr for NULL value.
    So the caller is able to determine the null value.
    This is only for the fetchAllRow interface, where later the caller need to 
call OutputInfo method get, instead of adding a new array to save null 
indicator, I choose to reuse the data_ pointer
