to run command to get bb output.

If a master job array record is complete, then consider all pending
tasks as also complete. This problem happens when a master job array
record is pending (has pending tasks) and is cancelled. The result
previously was a job record not visible to squeue/scontrol, but occupying
memory.
The same type of problem happened with respect to a dependency on a job
array which was cancelled.

This change will better reveal any vestigial job records not being purged

Add some parsing for interactive job support
Add parsing of Slurm set burst_buffer job field values

If a QOS was added for the job and then removed and it just happened
to be the largest QOS id wise if the slurmctld was restarted and the job
wasn't flushed out yet it could mess things up.
