When slurmctld processes a SIGHUP or "scontrol reconfig" it
makes sure that every pending batch job as a directory containing
script and environment files, cancelling any job that lacks the
files and purging any files without a job. When there are a large
number of jobs (in any state) and a large number of files, the
nested loops to do this can run for a very long time (minutes).
This change streamlines the processing for job arrays, which now
avoid creating their own script and environment files by using that
of their job array master record.

Release a job's allocated licenses only after epilog runs on all nodes
    rather than at start of termination process.

removes the kill_extern_procs() function added in the referenced commit.

This appears to be the way we do it with other steps and seems to work
correctly.

sched/backfill: This change moves some logic used to support the

SchedulerParameters now accepts keyword of "max_rpc_count" in

sched/backfill: If max_rpc_cnt is configured and the backlog of RPCs has
    not cleared after yielding locks, then continue to sleep.
