Statistics is not available for DECIMAL types

Add a configurableValueWriterFactory for parquet-hadoop module

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....
