Maintain UPDATE_TIME in information_schema.tables

[zhengwanbo]

Please answer these questions before submitting your issue. Thanks!

1. What did you do?

after crate a table, you can not get the CREATE_TIME and UPDATE_TIME from information_schema.tables.

2. What did you expect to see?

when you create table, tidb records the table create_time and update_time.

3. What did you see instead?

4. What version of TiDB are you using (tidb-server -V or run select tidb_version(); on TiDB)?
   mysql> select tidb_version();
   +-------------------------------------------------------------------------------------------------------------------------------------------------------------+
   | tidb_version() |
