Description

I think we should consider removing the min()/minBy()/max()/maxBy()/sum() utility methods from the DataStream API. They make the maintenance of the code unnecessary complicated, and don't add enough value for the users (who can not access the window metadata).

If we are keeping the methods, we should consolidate the min/minBy methods: the difference is subtle, and minBy can subsume the min method.
