> The GreedyReservationAgent allocates "as late as possible". Per various conversations,
it seems useful to have a mirror behavior that allocates as early as possible. Also in the
process we leverage improvements from YARN-4358, and implement an RLE-aware StageAllocatorGreedy(RLE),
which significantly speeds up allocation.
