-- Adds the specified Availability Zones to the set of Availability Zones
-- for the specified load balancer in EC2-Classic or a default VPC.
--
-- For load balancers in a non-default VPC, use
-- AttachLoadBalancerToSubnets.
--
-- The load balancer evenly distributes requests across all its registered
-- Availability Zones that contain instances. For more information, see
-- <https://docs.aws.amazon.com/elasticloadbalancing/latest/classic/enable-disable-az.html Add or Remove Availability Zones>
