Yeah, I think I agree here. The options I see are:

* Ironic train depends on 2.0.0. This breaks stable policy.
* We release 1.10.0 and depend on that. This breaks stable and release team
policy.
* We keep our dependencies the same and document that 1.9.0 is broken. This
breaks no policy.

The last option follows the letter of the law best, but doesn't actually
help our users. If they need to use 2.0.0 to have a working system anyway,
then the effect on users is the same as the first option, but in a
backwards way.

Let's just bring ironic to 2.0.0 and fix any breakage that comes with it.
