Thanks @uce! I extended the `RangePartitionRewriter` to cover that case and
will include the changes when I merge the PR.
I also found that no combiners are inserted if the input of a reduce or
combinable groupreduce is explicitly partitioned (FLINK-3179). This is not
directly related to this PR (because it also affects `partitionByHash` and
`partitionCustom`), but should be fixed soon.
I am trying the PR right now on a cluster setup. Thanks @ChengXiangLi for
your patience with this one!
