    Workaround for missing PBR requirement

    PBR misses a requirement to testrepository.
    This workaround installs it in front and can be removed after
    PBR is fixed.

    This fix also contains tox fix due to the fact that kilo gate is broken two
    times which can't be fixed in two dependent commits:

      Do not fail with Tox 2.3.1

      Latest tox causes failures:
         File "/usr/local/lib/python2.7/dist-packages/tox/config.py", line 1140, in processcommand
          argv = list(shlexer)
         File "/usr/lib/python2.7/shlex.py", line 269, in next
           token = self.get_token()
         File "/usr/lib/python2.7/shlex.py", line 96, in get_token
           raw = self.read_token()
         File "/usr/lib/python2.7/shlex.py", line 172, in read_token
           raise ValueError, "No closing quotation"
       ValueError: No closing quotation

      This is caused by a backwards incompatible change in tox:
