Async: move the actual task exection into Executor implementation

As of now, Job is only front interface to a chain of Executor subclasses. Each
Executor subclass specializes for given type of execution (then, each, reduce, ...),
and the chain is then executed recursively, as we did with the original Job
implementation.
