[SPARK-15674][SQL] Deprecates "CREATE TEMPORARY TABLE USING...", uses
"CREAT TEMPORARY VIEW USING..." instead
## What changes were proposed in this pull request?
The current implementation of "CREATE TEMPORARY TABLE USING..." is actually
creating a temporary VIEW behind the scene. We should just use "CREATE
TEMPORARY VIEW USING..." instead.
Example:
```
scala> spark.sql("CREATE temporary view my_tab7 (c1: String, c2: String)
USING org.apache.spark.sql.execution.datasources.csv.CSVFileFormat OPTIONS
(PATH '/Users/seanzhong/csv/cars.csv')")
scala> spark.sql("select c1, c2 from my_tab7").show()
+----+-----+
| c1| c2|
+----+-----+
|year| make|
|2012|Tesla|
...
```
It NOW prints a **deprecation warning** if "CREATE TEMPORARY TABLE
USING..." is used.
```
scala> spark.sql("CREATE temporary table my_tab7 (c1: String, c2: String)
USING org.apache.spark.sql.execution.datasources.csv.CSVFileFormat OPTIONS
(PATH '/Users/seanzhong/csv/cars.csv')")
16/05/31 10:39:27 WARN SparkStrategies$DDLStrategy: CREATE TEMPORARY TABLE
tableName USING... is deprecated, please use CREATE TEMPORARY VIEW viewName
USING... instead
```
