Support no_proxy environment variable

octokit uses faraday for making http_request.
There is a long standing issue in faraday to add support for the no_proxy environment variable: lostisland/faraday#247
Unfortuantely it seems like this is going nowhere.
A workaround is suggested in this issue: berkshelf/berkshelf#1341

The httpclient (and excon) farady adapter picks up proxy settings from the environment automatically.
