Review comment:
Unless we introduce at least a static factory method `TaskInfo.create(...)`,
I would keep these internal task name creation inside `TaskInfo` otherwise
Task constructor contains too many details. The same for
`taskNameWithSubtaskAndId`, I would rather pass the `executionAttemptID` to
`TaskInfo` constructor or again add a factory method with these details.
