Description

HIVE-19974 introduced backwards incompatible change, with SHOW TABLES statement showing only managed/external tables in the system.
This issue will restore old behavior, with SHOW TABLES showing all queryable entities, including views and materialized views.
Instead, to provide information about table types, SHOW EXTENDED TABLES statement is introduced, which includes an additional column with the table type for each of the tables listed.
Besides, the possibility to filter the show tables statements with a WHERE `table_type` = 'ANY_TYPE' clause is introduced.
