// Cancels an instance refresh that is in progress and rolls back any changes that
// it made. Amazon EC2 Auto Scaling replaces any instances that were replaced
// during the instance refresh. This restores your Auto Scaling group to the
// configuration that it was using before the start of the instance refresh. This
// operation is part of the instance refresh feature (https://docs.aws.amazon.com/autoscaling/ec2/userguide/asg-instance-refresh.html)
// in Amazon EC2 Auto Scaling, which helps you update instances in your Auto
// Scaling group after you make configuration changes. A rollback is not supported
// in the following situations:
//   - There is no desired configuration specified for the instance refresh.
//   - The Auto Scaling group has a launch template that uses an Amazon Web
//     Services Systems Manager parameter instead of an AMI ID for the ImageId
//     property.
//   - The Auto Scaling group uses the launch template's $Latest or $Default
//     version.
//
// When you receive a successful response from this operation, Amazon EC2 Auto
// Scaling immediately begins replacing instances. You can check the status of this
// operation through the DescribeInstanceRefreshes API operation.
