> We currently track allocated memory and allocated vcores per queue but we 
> don't have a good rate metric on how fast we're allocating these things. In 
> other words, a straight line in allocatedmb could equally be one extreme of 
> no new containers are being allocated or allocating a bunch of containers 
> where we free exactly what we allocate each time. Adding a resources 
> allocated per second per queue would give us a better insight into the rate 
> of resource churn on a queue. Based on this aggregated resource allocation 
> per queue we can easily have some tools to measure the rate of resource 
> allocation per queue.
