Solution

During the latest round of client-gen it found a bunch of deprecations

I think we'll need to figure out the best way to communicate these to customers

We don't plan on removing the deprecated methods anytime soon, so we could alternative choose to not remove them from opslevel-go either. If there's an option in the codegen to ignore deprecations, we could do that too.

@jasonopslevel - one of these deprecations has already caused customer confusion - the ManagerEmail field So i think it might be worth doing some of these things. I just need to think through the right away to go about this.
