* This is a massive patch that aims to clean up the codebase and bring it into compliance with HACKING.rst and PEP8 in one fell swoop. * Cleaned up use of gettext. * Updated log usage for consistency. * The tests run successfully against all plugins except cisco and nicira (due to dependency issues with these plugins). * Addresses bug 981208 Change-Id: I4d8c7ab138d8f7bb906d18dc34f88f8bd0581c19
