Support standalone testing & checking of modules

[NathanFlurry]

This ticket should be split in to sub-tickets.

Motivation

Modules currently need a test repo to be able to check any modules in development. This test repo also needs to include the config that's being tested, which makes it very hard to test multiple types of modules.

Implementation

• Needs to support specifying registry for dependencies
• Needs to support passing custom config to each test

Unsure what blockers we'll run in to when building the Project object.

Unsure where the gen folder will go for the entire project.
