> We will introduce {{getDescription()}} method which returns the description information of the ExecNode,
> introduce {{getOutputType()}} method which returns the output {{RowType}} of the ExecNode,
> introduce {{replaceInputEdge(int ordinalInParent, ExecEdge newInputEdge)}} method which can update the input edge at the given index.
> Note: {{RelNode}} also has {{getDescription()}} method, so before we finish all separation work, we will introduce {{getDesc()}} instead of {{getDescription()}} to avoid compile error.
