-- Removes the specified subnets from the set of configured subnets for the
-- load balancer.
--
-- After a subnet is removed, all EC2 instances registered with the load
-- balancer in the removed subnet go into the @OutOfService@ state. Then,
-- the load balancer balances the traffic among the remaining routable
-- subnets.
