As described in the [Task API](https://docs.aws.amazon.com/AmazonECS/latest/APIReference/API_Task.html), startedBy tag is useful for us to keep basic metadata about the task. We'd like it to be included in the [ECS Task Metadata](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task-metadata-endpoint-v4-response.html) in order to be able to receive it in tools like OpenTelemetry.
