> The Overseer work queues stored in ZK and abstracted by the Overseer can give
> us a good indication of the health of the cluster - if messages are taking
> too long to dequeue or the queue is growing too large, we know that the
> Overseer is overloaded and we are going to overwhelm the cluster.
>
> This work will add metrics to track the size of the Overseer queues (number
> of messages enqueued).
