   It seems that the `daemonContext` will close the socket of statsd.
   ```py
       return self.statsd.incr(stat, count, rate)
     File "/usr/local/lib/python3.8/site-packages/statsd/client/base.py", line 35, in incr
       self._send_stat(stat, '%s|c' % count, rate)
     File "/usr/local/lib/python3.8/site-packages/statsd/client/base.py", line 59, in _send_stat
       self._after(self._prepare(stat, value, rate))
     File "/usr/local/lib/python3.8/site-packages/statsd/client/base.py", line 74, in _after
       self._send(data)
     File "/opt/airflow/airflow/stats.py", line 40, in _send
       self._sock.sendto(data.encode('ascii'), self._addr)
   OSError: [Errno 9] Bad file descriptor
   ```
   
   A simple fix is to let stastd client load lazily.
