// Returns information about a stack drift detection operation. A stack drift
// detection operation detects whether a stack's actual configuration differs,
// or has drifted, from it's expected configuration, as defined in the stack
// template and any values specified as template parameters. A stack is considered
// to have drifted if one or more of its resources have drifted. For more information
// on stack and resource drift, see Detecting Unregulated Configuration Changes
// to Stacks and Resources (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-stack-drift.html).

// Use DetectStackDrift to initiate a stack drift detection operation. DetectStackDrift
// returns a StackDriftDetectionId you can use to monitor the progress of the
// operation using DescribeStackDriftDetectionStatus. Once the drift detection
// operation has completed, use DescribeStackResourceDrifts to return drift
// information about the stack and its resources.
