[packaging][7.0] pep8==1.5.7 is required

[Dmitry Teselkin]

It seems that 'pep8==1.4.6' causes errors 'Checker' object has no attribute 'blank_before'.

For example, periodic-keystone-python27-pkg-mos70 failed:
-----

The same job succeeded several days before because python-hacking Ubuntu package, that also installs pep8 as a dependency, was not installed and the latest version (pep8==1.5.7) from PyPI was used.
Logs: http://logs.mosi.mirantis.net/periodic-pkg/periodic-keystone-python27-pkg-mos70/486f095

hacking==0.8.1 requires pep8==1.4.5
hacking==0.9.0 requires pep8==1.5.6
hacking==0.10.1 requires pep8==1.5.7

During test run that faild hacking==0.10.1 was installed from MOS repository:
-----
15:01:01 698: python-hacking 0.10.1-0u~u14.04+mos1 0 1050 http://172.18.160.74/osci/mos/7.0/cluster/base/trusty/ trusty/main amd64 Packages
-----

So it seems that pep8==1.5.7 is also required for MOS=7.0
