[FLINK-3463] implement calc translation
This PR implements the `DataSetCalcRule`, so that filters, projections, and
their combinations are now translated to `FlinkCalc`s. `FlinkFilterRule`,
`FlinkProjectRule`, `DataSetFilterRule`, and `DataSetProjectRule` are removed.
@twalthr @fhueske let me know if that's what you had in mind :)
