> In order to help validate metric upgrade we first need to know what is new,
> what was removed, and what was changed. To help with this, we should add a
> new jmxtool which can dump the objects from JMX and diff them.
> Once we have this, we can also add a gold list of expected metrics and add
> tests to validate these metrics don’t change.
