`SHOW TABLE EXTENDED`
## What changes were proposed in this pull request?
Change the statement `SHOW TABLES [EXTENDED] [(IN|FROM) database_name] [[LIKE] 'identifier_with_wildcards'] [PARTITION(partition_spec)]` to the following statements:
- SHOW TABLES [(IN|FROM) database_name] [[LIKE] 'identifier_with_wildcards']
- SHOW TABLE EXTENDED [(IN|FROM) database_name] LIKE 'identifier_with_wildcards' [PARTITION(partition_spec)]
After this change, the statements `SHOW TABLE/SHOW TABLES` have the same syntax with that HIVE has.
## How was this patch tested?
Modified the test sql file `show-tables.sql`;
Modified the test suite `DDLSuite`.

'identifier_with_wildcards' statement
## What changes were proposed in this pull request?
Currently we haven't implemented `SHOW TABLE EXTENDED` in Spark 2.0. This PR is to implement the statement.
Goals:
1. Support `SHOW TABLES EXTENDED LIKE 'identifier_with_wildcards'`;
2. Explicitly output an unsupported error message for `SHOW TABLES [EXTENDED] ... PARTITION` statement;
3. Improve test cases for `SHOW TABLES` statement.
## How was this patch tested?
1. Add new test cases in file `show-tables.sql`.
2. Modify tests for `SHOW TABLES` in `DDLSuite`.
