Description

Once MESOS-9942 has landed, we can clean up and optimize the sorter for roles. Specifically, each node in the tree (except the root and virtual leaf node) will carry a back pointer to the role tree structure in the allocator. This will eliminate all the state duplications and unnecessary trackings that currently done inside the sorter.
