Is your feature request related to a problem or challenge? Please describe what you are trying to do.
Once apache/datafusion#750 is merged, UnresolvedShuffleExec and ShuffleReaderExec work correctly but they both report their output partitioning as unknown. This doesn't cause any functional issues because no further planning takes place that depends on this being correct, but this could be confusing to end users when viewing query plans. Also, in the future we may want to further optimize the plan during execution and this would require the output partitioning to be reported accurately.
Describe the solution you'd like
Populate the output partitioning in UnresolvedShuffleExec and ShuffleReaderExec and implement the associated serde code.
Describe alternatives you've considered
None
Additional context
None
