[SPARK-8118](https://github.com/apache/spark/pull/8196) implements redirecting Parquet JUL logger via SLF4J, but it is currently applied only when READ operations occurs. If users use only WRITE operations, there occurs many Parquet logs.
This PR makes the redirection work on WRITE operations, too.
**Before**
```scala
scala> spark.range(10).write.format("parquet").mode("overwrite").save("/tmp/p")
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

**After**
