Tested this vs. the current master and it works as expected. In the current
master, the metrics are not updated after the TM disassociates from the JM.
With this PR the reporter is closed, restarted and metrics are being reported
again.
In general, I'm wondering whether we should introduce an explicit suspended
state where the metrics are still available and only reset after recovery. I
was testing this with JMX and wondered whether it can be problematic for users
if the reporter are down during JM recovery.
