[SPARK-17620][SQL] Determine Serde by hive.default.fileformat when Creating
Hive Serde Tables
## What changes were proposed in this pull request?
Reopens the closed PR https://github.com/apache/spark/pull/15190
Make sure the hive.default.fileformat is used to when creating the storage
format metadata.
Output
``` SQL
scala> spark.sql("SET hive.default.fileformat=orc")
res1: org.apache.spark.sql.DataFrame = [key: string, value: string]
scala> spark.sql("CREATE TABLE tmp_default(id INT)")
res2: org.apache.spark.sql.DataFrame = []
```
Before
```SQL
scala> spark.sql("DESC FORMATTED tmp_default").collect.foreach(println)
..
[# Storage Information,,]
[SerDe Library:,org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe,]
[InputFormat:,org.apache.hadoop.hive.ql.io.orc.OrcInputFormat,]
[OutputFormat:,org.apache.hadoop.hive.ql.io.orc.OrcOutputFormat,]
[Compressed:,No,]
[Storage Desc Parameters:,,]
[ serialization.format,1,]
```
After
```SQL
scala> spark.sql("DESC FORMATTED tmp_default").collect.foreach(println)
..
[# Storage Information,,]
[SerDe Library:,org.apache.hadoop.hive.ql.io.orc.OrcSerde,]
[InputFormat:,org.apache.hadoop.hive.ql.io.orc.OrcInputFormat,]
[OutputFormat:,org.apache.hadoop.hive.ql.io.orc.OrcOutputFormat,]
[Compressed:,No,]
[Storage Desc Parameters:,,]
[ serialization.format,1,]
```
