    [SPARK-14184][SQL] Support native execution of SHOW DATABASE command and fix SHOW TABLE
to use table identifier pattern

    ## What changes were proposed in this pull request?
    
    This PR addresses the following
    
    1. Supports native execution of SHOW DATABASES command
    2. Fixes SHOW TABLES to apply the identifier_with_wildcards pattern if supplied.
    
    SHOW TABLE syntax
    ```
    SHOW TABLES [IN database_name] ['identifier_with_wildcards'];
    ```
    SHOW DATABASES syntax
    ```
    SHOW (DATABASES|SCHEMAS) [LIKE 'identifier_with_wildcards'];
    ```
    
    ## How was this patch tested?
    Tests added in SQLQuerySuite (both hive and sql contexts) and DDLCommandSuite
    
    Note: Since the table name pattern was not working , tests are added in both SQLQuerySuite
to
    verify the application of the table pattern.
