> At the moment, we use the {{JobManagerMetricGroup}} to report resource manager specific metrics such as the number of slots or registered {{TaskExecutors}}. Since the {{JobManagerMetricGroup}} is shared between the {{ResourceManager}} and the {{Dispatcher}} this prevents closing the {{JobManagerMetricGroup}} from the {{Dispatcher}}. 
> In order to solve this problem, I propose to introduce a {{ResourceManagerMetricGroup}} which is used by the {{ResourceManager}} to register resource manager specific metrics. In order to not break existing third party applications which rely on the current metrics layout, the {{ResourceManagerMetricGroup}} will use the scope and group name of the {{JobManagerMetricGroup}}.
