    soften statsd version requirement to allow v2

    We used to pin statsd to version 1.0.0. James E. Blair has written a
    few tests that now let us allow the current v2.0.1 version. To prevent
    unexpected upgrades, we disallow v3.0.0.

    Zuul scheduler only do very simple statsd operations. Testing with
    statsd 2.0.1:

    I have set up a basic listener:

     listener$ netcat -l 127.0.0.1 -p 666 --udp

    Then wrote the python script:

      import extras
      statsd = extras.try_import('statsd.statsd')

      statsd.incr('zuul.counter')
      statsd.timing('zuul.timer', 1234)
      statsd.timing('zuul.timer', 1)
      statsd.gaug:('zuul.gauge', 1234)

    Running it as:
      STATSD_HOST='127.0.0.1' STATSD_PORT=666 python statsd-test.py

    The listener gets:

      zuul.counter:1|czuul.timer:1234|mszuul.timer:1|mszuul.gauge:1234|g

    Sounds legit enough.

    Fix bug #1169599 'Zuul should depends on statsd 2 or later'
