> Implement and turn on the retraction for aggregates

> Key: FLINK-6091
> URL: https://issues.apache.org/jira/browse/FLINK-6091
> Project: Flink
> Issue Type: Sub-task
> Components: Table API & SQL
> Reporter: Shaoxuan Wang
> Assignee: Hequn Cheng
>
> Implement functions for generating and consuming retract messages for
> different aggregates.
> 1. add delete/add property to Row
> 2. implement functions for generating retract messages for unbounded groupBy
> 3. implement functions for handling retract messages for different aggregates.
> 4. handle retraction messages in CommonCorrelate and CommonCalc (retain
> Delete property).
> Note: Currently, only unbounded groupby generates retraction and it is
> working under unbounded and processing time mode. Hence, retraction is only
> supported for unbounded and processing time aggregations so far. We can add
> more retraction support later.
> supported now: unbounded groupby, unbounded and processing time over window
> unsupported now: group window, event time or bounded over window.
