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.
  • Property mode set to 100644
