[Yum] proxies suck

[seth vidal]

Hi Everyone,
 proxies suck. I hate them. They are the bane of my existence.
Unfortunately people have them and I'd like to get all the proxy
weirdness in one place so I can make some sense of it and maybe get it
fixed up some.

So please, if you have a bug with yum related to proxies and it's not
been fixed in the latest releases please add your input to:

http://devel.linux.duke.edu/bugzilla/show_bug.cgi?id=493

and cc yourself onto the bug.

Thanks
