Description

Currently, the ParquetDataset API itself still defaults to the legacy implementation (parquet.read_table already defaults to the new) and also still supports some keywords that won't be supported with the new implementation.

So if we want to remove the old implementation at some point (ARROW-15868), we should start deprecating those options, and also start defaulting to the new implementation when possible.
