Message:

FragmentQueue can now resubmit jobs.

• we keep an internal list of jobs currently being worked on. If the worker returns with a failure, they can be resubmit to the queue.
• there are Max_Attempts (currently set to 1) tries to resubmit.
• added unit test function on this.
• added regression test Fragmentation/Automation resubmitjobs.
