> TaskManager metrics are currently registered twice, once when the TaskManager is started
and once when the TaskManager associates with a JobManager.
> Originally the metrics were registered when the TM associates with the JM and unregistered
upon disassociation.
> 9e9776f17ed18b12af177e31ab0bc266236f85ef modified the {{TaskManager}} to use the {{TaskManagerServices}},
which when loaded _also_ register the metrics.
> I suggest to remove the registrations that happen upon (dis-)association.
