[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.
