Thanks @gallenvara for opening the PR. Looks mostly good but the tests need
to be improved, IMO.
It would also be good to extend the `DataDistribution` interface by adding
a method `TypeInformation[] getKeyTypes()`. This will allow us to validate the
key types of the `DataDistribution` and the specified keys in the
`PartitionOperator`.
> Support range partition with user customized data distribution.
