* cloudinit/distros/parsers/resolv_conf.py
added some pylint overrides with 'plXXXXX' syntax.
example: # pl51222 pylint: disable=E0102
The pl51222 there means: http://www.logilab.org/ticket/51222
This specific issue is present in 12.04 pylint, but not 13.04.
* pylint doesn't like the requests special handling we have.
which makes sense as it is only checking versus one specific version.
* general pep8 and pylint cleanups.
