Description

Shouldn't the missing bindings reported earlier in https://github.com/apache/arrow/pull/11632 be propagated higher up here in the parquet.py module?
Passing **kwargs as is the case for write_table would do the trick I think.
I am finding myself stuck while using pandas.to_parquet with use_legacy_dataset=false and no way to set the existing_data_behavior flag to overwrite_or_ignore
