Minor Description
We could want to enable/disable the root_prj_enforce flag on a per-nodemap basis. Indeed, it could be useful to be able to enforce root project quota for non-zero PROJID on the "tenant" nodemaps but not the "admin" nodemap, so that a storage administrator can clean up some mess that the tenant got themselves into.
One possibility could be to add a new rbac role that allows enforcing the project quota for the root user on a per-nodemap basis.
