// Detect drift on a stack set. When CloudFormation performs drift detection on a
// stack set, it performs drift detection on the stack associated with each stack
// instance in the stack set. For more information, see How CloudFormation
// performs drift detection on a stack set (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/stacksets-drift.html)
// . DetectStackSetDrift returns the OperationId of the stack set drift detection
// operation. Use this operation id with DescribeStackSetOperation to monitor the
// progress of the drift detection operation. The drift detection operation may
// take some time, depending on the number of stack instances included in the stack
// set, in addition to the number of resources included in each stack. Once the
// operation has completed, use the following actions to return drift information:
//   - Use DescribeStackSet to return detailed information about the stack set,
//     including detailed information about the last completed drift operation
//     performed on the stack set. (Information about drift operations that are in
//     progress isn't included.)
//   - Use ListStackInstances to return a list of stack instances belonging to the
//     stack set, including the drift status and last drift time checked of each
//     instance.
//   - Use DescribeStackInstance to return detailed information about a specific
//     stack instance, including its drift status and last drift time checked.
//
// For more information about performing a drift detection operation on a stack
// set, see Detecting unmanaged changes in stack sets (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/stacksets-drift.html)
// . You can only run a single drift detection operation on a given stack set at
// one time. To stop a drift detection stack set operation, use
// StopStackSetOperation .
