Description

For isolation of workloads across multiple sub-tenants of a filesystem, it would be useful to allow registering an NRS TBF rule for a nodemap. This can be proxied to some extent by setting a TBF rule for a project ID, but this doesn't work if there are multiple project IDs used by a single nodemap.
