### Describe the enhancement requested In `arrow/dataset/file_parquet.cc`, we have to set all Parquet ReaderProperties explicitly one by one from the source configuration, only because we cannot use the ReaderProperties copy constructor and afterwards set the MemoryPool to a different value: https://github.com/apache/arrow/blob/05c1a4bf545a560f2b118a2e6e6d3d6fa36a2716/cpp/src/arrow/dataset/file_parquet.cc#L71-L78 We should make MemoryPool settable on ReaderProperties, and then simplify the dataset code to use the ReaderProperties copy constructor. ### Component(s) C++, Parquet -- This is an automated message from the Apache Git Service.
