Parquet hard coded a JUL logger which always writes to stdout. This PR redirects it via SLF4j JUL bridge handler, so that we can control Parquet logs via `log4j.properties`. This solution is inspired by https://github.com/Parquet/parquet-mr/issues/390#issuecomment-46064909. Author: Cheng Lian <lian@databricks.com> Closes #8196 from liancheng/spark-8118/redirect-parquet-jul.
