FWIW, I've written about my experiences with the job_submit.lua plugin 
in the Wiki page 
https://wiki.fysik.dtu.dk/Niflheim_system/Slurm_configuration/#job-submit-plugins

My example plugin at 
https://github.com/OleHolmNielsen/Slurm_tools/tree/master/plugins may 
perhaps serve as inspiration.

Maybe you'll find some of that information useful?
