Add --cpus-per-task flag to APRUN commands

- Update to SLURM on Orion now requires jobs to explicitly state thread needs in APRUN/srun command at runtime, instead of exporting to environment and getting it from there. - Add "--cpus-per-task" flag with thread # to APRUN commands. Refs NOAA-EMC#2044
