// Terminates the specified instance and optionally adjusts the desired group
// size. This operation cannot be called on instances in a warm pool. This call
// simply makes a termination request. The instance is not terminated immediately.
// When an instance is terminated, the instance status changes to terminated . You
// can't connect to or start an instance after you've terminated it. If you do not
// specify the option to decrement the desired capacity, Amazon EC2 Auto Scaling
// launches instances to replace the ones that are terminated. By default, Amazon
// EC2 Auto Scaling balances instances across all Availability Zones. If you
// decrement the desired capacity, your Auto Scaling group can become unbalanced
// between Availability Zones. Amazon EC2 Auto Scaling tries to rebalance the
// group, and rebalancing might terminate instances in other zones. For more
// information, see Rebalancing activities (https://docs.aws.amazon.com/autoscaling/ec2/userguide/auto-scaling-benefits.html#AutoScalingBehavior.InstanceUsage)
// in the Amazon EC2 Auto Scaling User Guide.
