[SPARK-17932][SQL] Failed to run SQL "show table extended like table_name"
in Spark2.0.0
## 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. Improve test cases for `SHOW TABLES` statement.
Non-Goals:
1. Support `SHOW TABLES [EXTENDED] ... PARTITION` statement.
## How was this patch tested?
1. Add new test cases in file `show-tables.sql`.
2. Modify tests for `SHOW TABLES` in `DDLSuite`.
