Ability to select and delete multiple tables in the Datasource in Migrate

Currently, If there are multiple tables that have imported metadata to a Datasource in Migrate, and user decides this is a mistake, they have to delete each table one by one - in some cases this could be thousands of tables. If we could add the same check box process provided within Value Mapping page to the Datasource details page, it would make maintenance of this part of the system easier.
