            Reporter: Vasia Kalavri
            Assignee: Vasia Kalavri


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.
