// initiated, including their status, start time, 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. If a rollback is initiated while
// an instance refresh is in progress, Amazon EC2 Auto Scaling also returns
// information about the rollback of the instance refresh.
