-- Removes one or more load balancers from the specified Auto Scaling group.
--
-- 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.
