-- Deregisters a scalable target that was previously registered. If you are
-- no longer using a scalable target, you can delete it with this
-- operation. When you deregister a scalable target, all of the scaling
-- policies that are associated with that scalable target are deleted.
--
-- To create a new scalable target or update an existing one, see
-- < RegisterScalableTarget>.
