> In a federated environment, local impairments of one sub-cluster might
> unfairly affect users/queues that are mapped to that sub-cluster. A
> centralized component (GPG) runs out-of-band and edits the policies governing
> how users/queues are allocated to sub-clusters. This allows us to enforce
> global invariants (by dynamically updating locally-enforced invariants).
