PARQUET-1128: Upgrade the Apache Arrow version to 0.7.1 for SchemaConverter

[masayuki038]

When I converted parquet(1.9.1-SNAPSHOT) schema to arrow(0.4.0) with SchemaConverter, this exception raised.

java.lang.NoClassDefFoundError: org/apache/arrow/vector/types/pojo/ArrowType$Struct_

	at net.wrap_trap.parquet_arrow.ParquetToArrowConverter.convertToArrow(ParquetToArrowConverter.java:67)
	at net.wrap_trap.parquet_arrow.ParquetToArrowConverter.convertToArrow(ParquetToArrowConverter.java:40)
	at net.wrap_trap.parquet_arrow.ParquetToArrowConverterTest.parquetToArrowConverterTest(ParquetToArrowConverterTest.java:27)

This reason is that SchemaConverter refer to Apache Arrow 0.1.0.
I upgrade the Apache Arrow version to 0.7.1 for SchemaConverter.
