-- Detaches one or more Classic load balancers from the specified Auto Scaling group.
--
--
-- Note that this operation detaches only Classic load balancers. If you have Application load balancers, use 'DetachLoadBalancerTargetGroups' instead.
--
-- When you detach a load balancer, it enters the @Removing@ state while deregistering the instances in the group. When all instances are deregistered, then you can no longer describe the load balancer using 'DescribeLoadBalancers' . Note that the instances remain running.
