> Introduce a Cluster Manager that aggregates Load and Policy 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
