Description

Currently, `ValuesWriterFactory` could be config at `ParquetProperties`, but `ParquetOutputFormat` which is used by Hadoop and Hive haven't support to custom a ValuesWriterFactory. We should support update `ParquetOutputFormat` to support it.

Research direction

Start by reading ParquetOutputFormat and ParquetProperties, then trace how ValuesWriterFactory is currently configured. Done means Hadoop and Hive users can supply a custom ValuesWriterFactory through ParquetOutputFormat; no specific test file is named in the issue.
