Description

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.
