Joshua Harlow 911ada7bba Bring over the 'url_helper' module from bzr
This module is quite useful for fetching urls in a manner
that can be provided custom headers, retries and ssl_args
so let's ensure we have it available for usage under these
circumstances.

Also adds some basic sanity tests so that it will continue
to work as expected.
