This is about enabling tasks to mark themselves as candidates for resubmission during their execution on a node, for example when an error occured and was caught by the task.

The server already has the ability to resubmit individual tasks, in particular using the job sla's dispatch expiration settings. We need to provide an API in the tasks to set a "resubmit" flag, and have the node send that information in the job header, then have the server check for this flag.

If possible, the new API should not break the existing Task/AbstractTask API, so maybe it could be in a specialized subclass or interface, like "Resubmitable".
