[tor-relays] metrics

[Manager <ury.tor.abuse@xxxxxxxxx>]

    Hello,
      
      im trying to enable prometheus metrics, and... something goes
      wrong:
      
      torrc:
      MetricsPort 9166
      MetricsPortPolicy accept *
      
      after tor restart in logs:
      Tor[15368]: Opening Metrics listener on 127.0.0.1:9166
      Tor[15368]: Could not bind to 127.0.0.1:9166: Address already in
      use. Is Tor already running?
      
      -- before restart, no one listen on this port, as `ss | grep
      :9166` can say.
      
      there is also backtrace in logs:
      Tor[15368]: connection_finished_flushing(): Bug: got unexpected
