…ing tables
## What changes were proposed in this pull request?
Currently, `DROP TABLE IF EXISTS` shows warning for non-existing tables. However, it had better be quiet for this case by definition of the command.
**BEFORE**
```scala
scala> sql("DROP TABLE IF EXISTS nonexist")
16/11/20 20:48:26 WARN DropTableCommand: org.apache.spark.sql.catalyst.analysis.NoSuchTableException: Table or view 'nonexist' not found in database 'default';
```
**AFTER**
```scala
scala> sql("DROP TABLE IF EXISTS nonexist")
res0: org.apache.spark.sql.DataFrame = []
```
## How was this patch tested?
Manual because this is related to the warning messages instead of exceptions.
Author: Dongjoon Hyun <dongjoon@apache.org>
Closes #15953 from dongjoon-hyun/SPARK-18517.
(cherry picked from commit ddd02f5)
