    [SPARK-14396] [SQL] Throw Exceptions for DDLs of Partitioned Views

    #### What changes were proposed in this pull request?
    
    Because the concept of partitioning is associated with physical tables, we 
disable all the supports of partitioned views, which are defined in the 
following three commands in [Hive DDL 
Manual](https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-Create/Drop/AlterView):
    ```
    ALTER VIEW view DROP [IF EXISTS] PARTITION spec1[, PARTITION spec2, ...];
    
    ALTER VIEW view ADD [IF NOT EXISTS] PARTITION spec;
    
    CREATE VIEW [IF NOT EXISTS] [db_name.]view_name [(column_name [COMMENT 
column_comment], ...) ]
      [COMMENT view_comment]
      [TBLPROPERTIES (property_name = property_value, ...)]
      AS SELECT ...;
    ```
     
    An exception is thrown when users issue any of these three DDL commands.
    
    #### How was this patch tested?
    Added test cases for parsing create view and changed the existing test 
cases to verify if the exceptions are thrown.
