Issue MESOS-2764: Allow Resource Estimator to get Resource Usage information.
This includes two things: 1) We need to expose ResourceMonitor::Usage so that module writers can access it. We could define a protobuf message for that. 2) We need to allow ResourceEstimator to call 'ResourceMonitor::usages()'. We could either expose the ResourceMonitor, or pass in a lambda to the resources estimator.
