// Gets information about the instance refreshes for the specified Auto Scaling
// group. 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. To help you determine the
// status of an instance refresh, this operation returns information about the
// instance refreshes you previously initiated, including their status, end time,
// the percentage of the instance refresh that is complete, and the number of
// instances remaining to update before the instance refresh is complete. The
// following are the possible statuses:
//
// * Pending - The request was created, but
// the operation has not started.
//
// * InProgress - The operation is in progress.
//
// *
// Successful - The operation completed successfully.
//
// * Failed - The operation
// failed to complete. You can troubleshoot using the status reason and the scaling
// activities.
//
// * Cancelling - An ongoing operation is being cancelled.
// Cancellation does not roll back any replacements that have already been
// completed, but it prevents new replacements from being started.
//
// * Cancelled -
// The operation is cancelled.
