--------------------------------------
bq. Can do in a sub issue of this one.
This ticket became a specific fix, so I renamed it thusly. Let's definitely
open more for further improvements.

> Over on HBASE-12911 I have a patch that registers Connection instances with
> the metrics system. In both standalone server and tll client applications, I
> was surprised to see multiple connection objects showing up that are unused.
> These are pretty heavy objects, including lots of client threads for the
> batch pool. We should track these down and remove them -- if they're not some
> kind of phantom artifacts of my WIP patch over there.
