-- 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:
--
-- 1.  Create a notification target. A target can be either an Amazon SQS
--     queue or an Amazon SNS topic.
-- 2.  Create an IAM role. This role allows Auto Scaling to publish
--     lifecycle notifications to the designated SQS queue or SNS topic.
-- 3.  Create the lifecycle hook. You can create a hook that acts when
--     instances launch or when instances terminate.
-- 4.  If necessary, record the lifecycle action heartbeat to keep the
--     instance in a pending state.
-- 5.  __Complete the lifecycle action__.
