So, I'm not thrilled about this, but after a bunch of back-and-forth
on IRC, I think I'm comfortable with us doing this as a 1-off, while
upstream gets their release schedule back in order. If they continue
to slip in the future, we'll have to re-evaluate.

We do want to be as close to 100% certain as we can be that the deps
are finalised by release. If that means throwing very late snapshots
at the queue during release week, that's fine as long as they're not
being shipped on any media (you can check this with the poorly-named
seeded-in-ubuntu tool in ubuntu-dev-scripts).

So, a very grumpy +1 from me. Let us try to do this as painlessly as
we can manage, and make sure we have a solid OpenStack story for the
20.04.1 point release.
