> The current metrics library which Kafka is using is pretty old (version 2.2.0 from Yammer and now we have 4.X from Dropwizard).
> In the latest versions of the Dropwizard library (which comes from Yammer and this is deprecated), there are a lot of bugfixes and new features included which could be interesting for the metrics (ie: Reservoris, support JDK9, etc).
> This patch includes the upgrade to this new version of the library so that we could add new features in Kafka metrics.
