Altair Accelerator Plus Agent Preemption

vovtasker understands Signal USR1 as killing all the jobs running on it and exiting as soon as possible. This signal can be used to preempt Accelerator Plus agents running on an Accelerator queue. When an Accelerator Plus agent receives a USR1, it kills all jobs, and sets the states of jobs as WITHDRAWN. These jobs get rescheduled in Accelerator Plus and will be dispatched on a new tasker. The Accelerator Plus agent on Accelerator exits and becomes a valid job. The following is an example to preempt an Accelerator Plus agent job on Accelerator.
