Make ParquetReader(List<InputFile>, ParquetReadOptions, ReadSupport<T>) constructor public

[asfimport]

My application uses s3 storage to store parquet files. The problem is that there is not ability to get rid from new Configuration(true); which load configuration from files:
core-default.xml and core-site.xml every time when ParquetReader instance is created.

I suggest just make ParquetReader(List, ParquetReadOptions, ReadSupport) constructor public then there will be ability to do custom builder.
