[ovirt-users] Additional user in ovirt-node-ng 4.x

Hello, my colleague is asking if is possible to define a certain user on our hosts. I know that the rule is to avoid installations and changes to hosts running ovirt-node, but in this case the user creation should have a very minimum impact. He's running HP uCMDB that makes an ssh connection to the host for grabbing some system information to populate it's DB. Is possible to create a new user? Does this user is preserved with upgrades? Is possible also to allow this new user to run 4 (exactly 4) commands through sudo?
