~ubuntu-server subscription changes

[Bryce Harrington]

Robie,

Interesting!  I happened to run into this same stacktrace trying to run
one of the smoketests for ppa-dev-tools.  In my case, I ran into this
only when running against the qastaging Launchpad service during
testing, however I'm guessing your tool runs against production.

The "Unable to find the server at api.launchpad.test" error suggests
something's trying to access a non-existant test Launchpad URI.  This
isn't in the launchpadlib codebase, but is present in launchpad itself.
However it's not at all clear to me how or why this triggers.  If you
figure something out I'd be interested to know.

My original guess was that it was some peculiarity regarding qastaging
and how credentials are cached, since I started using qastaging just a
couple weeks ago and 2 weeks sounds on the order of a cache timeout.
However, if you're also seeing it, my hypothesis is probably wrong.  I
wonder if something has changed on the Launchpad end?
