> 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
