[slurm-users] partition qos without managing users

ok, I understand synching of users to slurm database is a task which it 
not built-in, but could be added outside of slurm :-)

With regards to the QoS or Partition QoS setting I've tried several 
settings and configurations however it was not possible at all to 
configure a QoS on partition level only without not adding specific 
users to the slurm database.
Either I don't understand the docs properly or there is no configuration 
option to limit jobs with e.g. cpu=4 globally on a partition.

Could anybody share a configuration which set partition QoS (e.g. cpu=8) 
without managing users or a configuration to silently change the job QoS 
using job_submit.lua again without maintaining users within slurm
