> We introduce the notion of an RMProxy, running on each node (or once per rack). Upon
start the AM is forced (via tokens and configuration) to direct all its requests to a new
services running on the NM that provide a proxy to the central RM. 
> This give us a place to:
> 1) perform distributed scheduling decisions
> 2) throttling mis-behaving AMs
> 3) mask the access to a federation of RMs
