TAJO-1642: CatalogServer need to check meta table first.
I tested this patch on my laptop. When I tried to start up
tajo-0.11.0-SNAPSHOT with the catalog-site.xml file for tajo-0.10.1-SNAPSHOT,
TajoMaster printed following messages.
```
15/06/09 11:38:11 INFO store.MySQLStore: The meta table of CatalogServer
already is created.
15/06/09 11:38:11 ERROR store.MySQLStore: Catalog version (2) and current
driver version (4) are mismatch to each other
15/06/09 11:38:11 ERROR store.MySQLStore:

15/06/09 11:38:11 ERROR store.MySQLStore: | Catalog Store Migration Is
Needed |

15/06/09 11:38:11 ERROR store.MySQLStore: | You might downgrade or upgrade

15/06/09 11:38:11 ERROR store.MySQLStore: | Tajo without migration process
is only available in some versions. |
15/06/09 11:38:11 ERROR store.MySQLStore: | In order to learn how to
migration Apache Tajo instance, |
15/06/09 11:38:11 ERROR store.MySQLStore: | please refer
http://s.apache.org/0_8_migration. |
15/06/09 11:38:11 ERROR store.MySQLStore:

```
And I found that existing column informations exists normally. For the
reference, I succeed to test with only tajo-0.11.0-SNAPSHOT.
