will make it so the slurmctld will not signal the apid's in a batch job.
Instead it relies on the rpc coming from the slurmctld to kill the job to

Refactor scancel so that all pending jobs are cancelled before starting
cancellation of running jobs. Otherwise they happen in parallel and the
pending jobs can be scheduled on resources as the running jobs are being
cancelled.

Add SchedulerParameters option of sched_min_interval that controls the
minimum time interval between any job scheduling action. The default value
