* option2: implement throwing exception if async_job table pending jobs exceed the threshold for migration

* option1: use the sync_queue mechanism to limit execution per DS

This uses the ideal way that must be accepted by the community that uses
the sync_queue + the global setting via API dispatcher to enforce the
number of async API jobs executed for a sync Obj ID (datastore in our cases).
This is much cleaner implementation but involves changes to the
job framework, in case of any regressions we'll partially revert this
commit and aim to fix this during community submission.
