Description

With FLINK-8749, we introduced that a ConjunctFutures cancels all of its input futures if it is cancelled. This has, however, some unpleasant side effects since a all of the cancelled future's completing callbacks won't be called. Since this can lead to subtle bugs like in FLINK-9908, I would propose to remove this feature and require the user to do the cancellation of input futures explicitly.
