Three CI builds in the last 48 hours have failed because launchpad had a lie down

[David Cheney]

We already have godeps which can take a set of vcs repos and flick
them to the right revisions.

Why does CI check out every single dependency from upstream every
single time we do a build ? That introduces wc -l dependencies.tsv
points of failure to every single CI run -- not to mention the several
minutes it spends laboriously checking out the code.

Thanks
