Consider making a Deployer contract to do all the initial setup steps

We have quite a few steps of passing the same arguments to lots of different contracts. This ends up requiring us to have a lot of duplicated code in deploy scripts, forge tests and javascript tests. Consider making a deployer contract to do that whole initial deployment. That way if that code is correct, we can be confident that our deployment is correct and we don't have to audit a lot of deployment code as well as solidity code.
