[SPARK-16221][SQL] Redirect Parquet JUL logger via SLF4J for WRITE
operations
## What changes were proposed in this pull request?
[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>
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.
