> This task implements the optimization of logical Table API plans with Apache Calcite. The input of the optimization process is a logical query plan consisting of Calcite RelNodes. FLINK-3223 translates Table API queries into this representation.
> The result of this issue is an optimized logical plan.
> Calcite's rule-based optimizer applies query rewriting and optimization rules. For Batch SQL, we can use (a subset of) Calcite’s default optimization rules. 
> For this issue we have to 
> - add the Calcite optimizer to the translation process
> - select an appropriate set of batch optimization rules from Calcite’s default rules. We can reuse the rules selected by Timo’s first SQL implementation.
