-- Removes one or more instances from the specified Auto Scaling group.
--
-- After the instances are detached, you can manage them independent of the
-- Auto Scaling group.
--
-- If you do not specify the option to decrement the desired capacity,
-- Amazon EC2 Auto Scaling launches instances to replace the ones that are
-- detached.
--
-- If there is a Classic Load Balancer attached to the Auto Scaling group,
-- the instances are deregistered from the load balancer. If there are
-- target groups attached to the Auto Scaling group, the instances are
-- deregistered from the target groups.
