// Deregisters the specified targets from the specified target group. After the
// targets are deregistered, they no longer receive traffic from the load balancer.
//
// The load balancer stops sending requests to targets that are deregistering, but
// uses connection draining to ensure that in-flight traffic completes on the
// existing connections. This deregistration delay is configured by default but can
// be updated for each target group.
//
