Maru Newby c552626664 Update codebase for HACKING compliance.
* 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
