[SPARK-23229][SQL] Dataset.hint should use planWithBarrier logical plan ## What changes were proposed in this pull request? Every time `Dataset.hint` is used it triggers execution of logical commands, their unions and hint resolution (among other things that analyzer does). `hint` should use `planWithBarrier` instead.
