-- | Completes the lifecycle action for the associated token initiated under the
-- given lifecycle hook with the specified result.
--
-- This operation is a part of the basic sequence for adding a lifecycle hook
-- to an Auto Scaling group:
--
-- Create a notification target. A target can be either an Amazon SQS queue or
-- an Amazon SNS topic. Create an IAM role. This role allows Auto Scaling to
-- publish lifecycle notifications to the designated SQS queue or SNS topic. Create the lifecycle hook. You can create a hook that acts when instances launch or when instances terminate.
-- If necessary, record the lifecycle action heartbeat to keep the instance in
-- a pending state.  Complete the lifecycle action.  For more information, see <http://docs.aws.amazon.com/AutoScaling/latest/DeveloperGuide/AutoScalingPendingState.html Auto Scaling Pending State> and <http://docs.aws.amazon.com/AutoScaling/latest/DeveloperGuide/AutoScalingTerminatingState.html Auto Scaling Terminating State> in the /Auto Scaling Developer Guide/.
