>   Currently, The "TwoInputStreamOperator" such as 
> "CoBroadcastWithKeyedOperator" "KeyedCoProcessOperator" and the
>  (Co)stream such as "ConnectedStreams" "BroadcastConnectedStream" only 
> support compute watermark by two stream.
>  but user just need one stream to compute watermark in some case.
>       For example: one stream is only rule data or control command, it
>  don't hava event time.
>  I think user has right to choose which stream to compute watermark.
