> Introduce a Cluster Monitor that aggregates load information from individual
> Node Managers and computes an ordered list of preferred Node managers to be
> used as target Nodes for OPPORTUNISTIC container allocations.
> This list can be pushed out to the Node Manager (specifically the AMRMProxy
> running on the Node) via the Allocate Response. This will be used to make
> local Scheduling decisions
