Adding a new field to the runAsync method

[Jacopo Cappellato]

I would like to specify a job name for the jobs submitted using the
runAsync method (in a similar way the dispatcher.schedule(...) does).

What about adding a new optional field to the runAsync method calls to
explicitly set the jobName?
This information should be stored in the JobSandbox.jobname field if the
job is persisted.
This would obviously need a change to the LocalDispatcher interface
(adding a new overloaded runAsync method) and so it is a pretty
important change.
