> When quota is assigned in the role hierarchy (see MESOS-6375), it's possible for there to be "undelegated" quota for a role. For example:
> {noformat}
>                     ^
>                   /   \
>                 /       \
>        eng (90 cpus)   sales (10 cpus)
>              ^
>            /   \
>          /       \
>  ads (50 cpus)   build (10 cpus)
> {noformat}
> Here, the "eng" role has 60 of its 90 cpus of quota delegated to its children, and 30 cpus remain undelegated. We need to design how to allocate these 30 cpus undelegated cpus. Are they allocated entirely to the "eng" role? Are they allocated to the "eng" role tree? If so, how do we determine how much is allocated to each role in the "eng" tree (i.e. "eng", "eng/ads", "eng/build").
