Description

HIVE-2989 introduces the concept of table links into Hive.
In this improvement, we will continue the support for table links by handling cases where the source of the table link is dropped/renamed.

When the source of a table link is dropped via DROP TABLE, the behavior will be that all table links that point to it, are dropped as well.

When the source of a table link is renamed via ALTER TABLE ... RENAME ..., the behavior will be that all table links that point to it are renamed from T@Y to T1@Y where the table T was renamed to T1.
