> Add TumbleRow row-windows for streaming tables as described in [FLIP-11|https://cwiki.apache.org/confluence/display/FLINK/FLIP-11%3A+Table+API+Stream+Aggregations]. 
> TumbleRow row windows are a syntactic shortcut for a special type of SQL OVER windows, i.e., windows of the from 
> {code}
> SELECT STREAM rowtime,
>   productId,
>   units,
>   SUM(units) OVER (PARTITION BY FLOOR(rowtime() TO HOUR)) AS unitsSinceTopOfHour
> FROM Orders;
> {code}
> i.e., OVER windows which are partitioned by the time attribute. 
> This issue is about extending the Table API with the TumbleRow shortcut. It should reuse the OVER window translation and runtime code implemented by FLINK-5653, FLINK-5654, FLINK-5655, FLINK-5656, FLINK-5657, and FLINK-5658.
