-- Modifies the attributes of the specified load balancer.
--
-- You can modify the load balancer attributes, such as 'AccessLogs',
-- 'ConnectionDraining', and 'CrossZoneLoadBalancing' by either enabling or
-- disabling them. Or, you can modify the load balancer attribute
-- 'ConnectionSettings' by specifying an idle connection timeout value for
-- your load balancer.
