> Implement CatalogStore::updateTableStats

> Currently, there is no method to update existing table information at
> CatalogStore. So, if user execute an insert query, tajo drop a table and then
> tajo create a table. It doesn't matter to tajo own CatalogStore like
> DerbyStore, MySQLStore. But it is a critical issue to HCatalogStore. if tajo
> drop a existing partitioned table, users will lose existing partition
> informations. As a result, they should repair table partition against their
> will. As you know, hive msck command can affect hive metastore performance.
