Gate fails on gate-python-cinderclient-pep8

[Tomoki Sekiyama]

Currently the pep8 in the gate is failing by the error:

2015-05-26 07:43:33.724 | pkg_resources.VersionConflict: (pbr 1.0.1 (/home/jenkins/workspace/gate-python-cinderclient-pep8/.tox/pep8/lib/python2.7/site-packages), Requirement.parse('pbr<1.0,>=0.5.21'))

This is because pbr 1.0.1 has released and although most of the dependencies in have switched to:

 pbr>=0.11,<2.0

we are still using the hacking module from last year (hacking>=0.8.0,<0.9), which has pbr pegged to <1.0.

The hacking module must be bumped and the new rules ignored.

    Bump hacking to >=0.10.0,<0.11 to fix failure of gate pep8

    pbr 1.0.1 released in 2015-05-19 requires the newer
    hacking module >=0.10.0,<0.11 than the versions
    specified in the test-requirement.txt file,
    which causes failure in gate-python-cinderclient-pep8.

    This patch bumps the pbr version in test-requirement.txt
    to make it consistent with requirements repository,
    and adds some fixups to avoid some new hacking rules.
