> OOZIE-1817 added the option to use DropWizard Metrics instead of our homegrown Instrumentation. We left the Instrumentation as the default for compatibility; in Oozie 5.1.0, we should drop Instrumentation and only have Metrics.
> OOZIE-2645 deprecated {{Instrumentation}} and made {{Metrics}} the default choice, but no code cleanup happened there.
> We can also use this opportunity to clean up the code and interface for Metrics, which currently has to conform to Instrumentation for pluggability.
