Adding ability to override classes

[rambleraptor]

This will let us override types. For example, TF could have a
property act as a String, while everything else treats it as a
ResourceRef...

I am a robot that works on MagicModules PRs!

I built this PR into one or more PRs on other repositories, and when those are closed, this PR will also be merged and closed.
depends: modular-magician/ansible#92
depends: GoogleCloudPlatform/puppet-google-compute#94

^ both of those PRs have correct code, but I'm not sure where they came from. I'll investigate later.

I was going to complain about the lack of tests but apparently the entire api module has no tests so ¯_(ツ)_/¯

[rambleraptor]

Yeah, we don't have a great story there. We need a much better one.

I did some manual tests and it works as intended.

Sure, seems reasonable. It would be nice to have this link to an issue or some other form of context so when someone looks at it later, they can tell why this change was made.

More context there. I can't go into very specific detail in GH.
