CI hates juju, maybe the feelings are mutual

[Curtis Hovey-Canonical]

I am exhausted, so I am sending out the barest summary of the Juju-CI
problems I see.

^ In  general, if the test doesn't end in -devel or start with walk-,
we require the test to pass.

lp:juju-core/trunk r2593 could not upgrade because of an exception.
Note that this rev precedes the rev that makes it impossible to
downgrade. I see new revisions queue, may trunk will pass while I
sleep

lp:juju-core/1.18 r2264 and subsequent revscould not upgrade hp,
joyent, azure, or aws. some of the agents failed to update. This
results for the different CPC are consistent. I see the change relates
to not permitting downgrades. Damn, I just submitted pull request
documenting that you can downgrade.
