> 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.
