--
-- Deletes the specified Auto Scaling group.
--
-- If the group has instances or scaling activities in progress, you must
-- specify the option to force the deletion in order for it to succeed. The
-- force delete operation will also terminate the EC2 instances. If the
-- group has a warm pool, the force delete option also deletes the warm
-- pool.
--
-- To remove instances from the Auto Scaling group before deleting it, call
-- the DetachInstances API with the list of instances and the option to
-- decrement the desired capacity. This ensures that Amazon EC2 Auto
-- Scaling does not launch replacement instances.
--
-- To terminate all instances before deleting the Auto Scaling group, call
-- the UpdateAutoScalingGroup API and set the minimum size and desired
-- capacity of the Auto Scaling group to zero.
--
-- If the group has scaling policies, deleting the group deletes the
-- policies, the underlying alarm actions, and any alarm that no longer has
-- an associated action.
--
-- For more information, see
-- <https://docs.aws.amazon.com/autoscaling/ec2/userguide/as-process-shutdown.html Delete your Auto Scaling infrastructure>
