Code review comment for lp:~cjwatson/lazr.restfulclient/lsb-release

I noticed today that there's a "distro" module on PyPI and in Debian which is actively maintained and provides much the same interface as was previously in the stdlib, but including more modern data sources such as os-release. I'm therefore withdrawing this MP in favour of https://code.launchpad.net/~cjwatson/lazr.restfulclient/distro/+merge/344799.
