pep8 errors "openstack_dashboard" subdirectory

[Radomir Dopieralski]

While fixing https://bugs.launchpad.net/horizon/+bug/1347472 "Re-enable disabled pep8 errors" around 2 500 pep8 errors occurred. Since there are many of them this particular bug will solve the "openstack_dashboard" subdirectory and there will be other bugs to fix all the issue before bug https://bugs.launchpad.net/horizon/+bug/1347472 is closed.
