    [FLINK-5624] Support tumbling window on streaming tables in the SQL API.

    This is a POC to add tumbling window support for streaming tables in SQL.
    
    Essentially it recognizes the `LogicalWindow` construct in Calcite and transform it to
the `LogicalWindowAggregate` in flink.
    
    Feedbacks are highly appreciated.
