Actually I think we’ll need to wait for the FE/BE/docs to go out before merging :/

New Changes

• Removed the init_config.toml
• Added tests

The backend is now merged and I'm hoping to get this in so that we can allow contributors to write examples for custom SMS providers

How this was tested?

• Without any hooks to ensure it's compatible
• With a hook to ensure it loads as expected

Might want to add a valid config to init_config.test.toml as a sanity check.
