Issue MESOS-2893: Add queue size metrics for the allocator.
In light of the performance regression in MESOS-2891, we'd like to have visibility into the queue size of the allocator. This will enable alerting on performance problems. We currently have no metrics in the allocator. I will also look into MESOS-1286 now that we have gcc 4.8, current queue size gauges require a trip through the Process' queue.
