Description

As a first step for ARROW-9720, we should start with deprecating attributes/methods of pq.ParquetDataset that we would definitely not keep / are conflicting with the "dataset API".

I am thinking of the pieces attribute (and the ParquetDatasetPiece class), the partitions attribute (and the ParquetPartitions class).

In addition, some of the keywords are also exposed as properties (memory_map, read_dictionary, buffer_size, fs), and could be deprecated.
