> Would be nice to add some metrics for each of the executor services in the master and
region server:
> - number of items in the queue
> - age of the oldest yet-unprocessed item (ie in the queue or currently being handled)
> - number of threads in the executor currently busy
> These would allow us to monitor better for cases where things get "stuck"
