Would be good if Replication didn't put up a Connection till it had something 
to Connect to.

> 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.
