Async: implement progress reporting through future

This is a simplified progress reporting, since it does not report progress
of ther overcall Job chain, but only of individual tasks, which makes it
only really useful on one-task Jobs.

TODO: propagate subjob progress to the Future user gets copy of
TODO: compound progress reporting (be able to report a progress of the overall
      Job chain)
