[SPARK-21786][SQL] When acquiring 'compressionCodecClassName' in
'ParquetOptions', `parquet.compression` needs to be considered.
## What changes were proposed in this pull request?
1.Increased acquiring 'compressionCodecClassName' from
`parquet.compression`,and the precedence order is
`compression`,`parquet.compression`,`spark.sql.parquet.compression.codec`, just
like what we do in `OrcOptions`.
2.Change `spark.sql.parquet.compression.codec` to support "none".Actually
in `ParquetOptions`,we do support "none" as equivalent to "uncompressed", but
it does not allowed to configured to "none".
3.Change `compressionCode` to `compressionCodecClassName`.
## How was this patch tested?
Add test.
