    [FLINK-4231] [java] Switch DistinctOperator from GroupReduce to Reduce

    Rewrite the DistinctOperator using Reduce to support both the sort-based combine and the
recently added hash-based combine. This is configured by the new method DistinctOperator.setCombineHint(CombineHint).
        
    The tests for combineability are removed as Reduce is inherently combineable.
