Define constants in separate module

[JonathonMA]

This avoids a constant redefinition warning if the build.rake file is loaded twice (which, in our case, is more than annoying since we raise on warnings in development and test mode!)

Could you post the actual warning you avoiding with this?

[JonathonMA]

Sure, in our case we are using the handcuffs gem to allow phased migrations, which I believe is calling Rails.application.load_tasks a second time, which ends up looking something like this:

$ bin/rails db:test:load handcuffs:migrate[all]

We're seeing the same warnings in a project I'm working on. Thanks for fixing this!

Sorry, needs a rebase.
