-- Detaches one or more Classic Load Balancers from the specified Auto
-- Scaling group.
--
-- This operation detaches only Classic Load Balancers. If you have
-- Application Load Balancers, Network Load Balancers, or Gateway Load
-- Balancer, use the DetachLoadBalancerTargetGroups API 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
-- the DescribeLoadBalancers API call. The instances remain running.
