> There is a list of  outputSelector in streamNode and streamOperator. 
> Every outputSelector returns  a string list:
>   
> {code:java}
>  Iterable<String> select(OUT value);
> {code}
> then string results of all  outputSelectors will be unioned in the streamTask when outputing a record.
> So I want to introduce CombineOutputSelector to union these results, and only one OutputSelector is needed in streamNode and streamOperator.
