Identity information for the Amazon EC2 instance that is hosting the task runner. You can get this value by calling the URI,
            http://169.254.169.254/latest/meta-data/instance-id, from the EC2 instance. For more information, go to Instance Metadata in the Amazon
            Elastic Compute Cloud User Guide. Passing in this value proves that your task runner is running on an EC2 instance, and ensures the
            proper AWS Data Pipeline service charges are applied to your pipeline.
