[baisui1981]

In order to adopt Chunjun Source and Sink connector into TIS framework ，We need to customized selected table properites when define the data pipeline with Chunjun Source / Sink.

For example, a pipeline with Chunjun source , it is need to define the table polling strategy ，with polling time interval ，whether to use Max function ，and so on

添加 IncrSelectedTabExtend.java ，当source或者sink需要扩展 Selected table 则只需要将Describle (TISSinkFactory.BaseSinkFunctionDescriptor ChunjunSourceFactory.BaseChunjunDescriptor )实现 IIncrSelectedTabExtendFactory 接口即可
