resources to framework in roles with quota set. Once all quotas are
satisfied, it proceeds with the standard wDRF for all frameworks.

+ resources beyond its quota guarantee. If frameworks in the quota'ed
+ role have not opted for revocable resources, they may stop getting

If there are multiple frameworks in a role with quota set, the standard wDRF
algorithm determines framework priority inside this role.
