Nailgun's python-keystoneclient do not satisy python-cinderclient 's requirement

[Sebastian Kalinowski]

When calling any script in nailgun, we have conflict in requirements:

 - Traceback (most recent call last):
  File ".tox/venv/bin/manage.py", line 5, in <module>
    from pkg_resources import require
  File "/home/jenkins/workspace/verify-python-fuelclient/fuel-web/nailgun/.tox/venv/local/lib/python2.7/site-packages/pkg_resources.py", line 2720, in <module>

    raise VersionConflict(dist,req) # XXX put more info here
pkg_resources.VersionConflict: (python-keystoneclient 1.4.0 (/home/jenkins/workspace/verify-python-fuelclient/fuel-web/nailgun/.tox/venv/lib/python2.7/site-packages), Requirement.parse('python-keystoneclient>=1.6.0'))

It is casued by python-cinderclient 1.2.2 that required python-keystoneclient >= 1.6.0 and we install 1.4.0

    Pin upper bound of python-cinderclient version

    python-cinderclient > 1.2.1 require python-keystoneclinet 1.6 when we install
    1.4 due to fix problem with pbr version caused by keystonemiddleware
    We could require higher versiona of keystonemiddleware (>=1.5) but it
    would be much higher than the version we have in repos (1.2) for 6.1
