Create specialized HadoopParquetReader

[asfimport]

Setting up a specialized HadoopParquetReader allows for deprecating the Hadoop specific methods in ParquetReader as in PARQUET-2381. This could allow for an easier and more gentle transition away from the current Hadoop-coupled Parquet reader API by encouraging transitioning to this specialized class already, before completely phasing out the Hadoop methods from ParquetReader in the future.
