[Python] Expose group by function

1. The hash_aggregate functions are in pyarrow.compute, but they're not
directly callable. Looks like GroupBy is unavailable in Python.
2. Can you provide an example of hash_sum from pc.compute?

Thanks

There is an open pull request (https://github.com/apache/arrow/pull/11624)
to expose these.  They should be accessible in  Arrow 7.0.
