> After discussion with [~fhueske], [~chengxiang li], and [~twalthr], we have decided to
make the following refactoring:
> - Make the DataSet RelNodes correspond to logical relational operators.
> - Move the code generation from the rules into the DataSet RelNodes.
> - Remove the Flink RelNode layer and have a 1-pass translation instead of a 2-pass translation
as currently.
