We should rename the configuration item proxy_url to proxy_host in the DownloadConfig so that it's not misleading.
proxy_url has already been renamed to proxy_host in all repositories outside of nectar. Nectar is still using the proxy_url as a url as opposed to a hostname so it makes sense to be calling it a URL in context of the nectar config. The pulp server is mapping proxy_host to proxy_url in pulp/server/pulp/plugins/util/nectar_config.py No change needs to be made for this bug.
