	This refactors code to handle partial machine config - only multi-doc without v1alpha1 config. This uses improvements from https://github.com/cosi-project/runtime/pull/300: * where possible, use `TransformController` * use integrated tracker to reduce boilerplate Sometimes fix/rewrite tests where applicable.
