[Yum] Changing user agent string

[dac at proofpoint.com (Dan Christian)]

Is there a way to change the user agent string?

Some people severely limit which agents are allowed through a proxy.

It seems to be set in clientStuff.py:35:
# it would be nice to make this slurp the REAL version from somewhere :)
urlgrabber.set_user_agent("Yum/2.X")

I'm not on the list.  Please CC me.

Thanks,
