Per editor Connect support v0.1

- Basic plumbing to support connections for a URI rather than global connections. Typical use case is editor requests to connect, but this isn't the only possible use
- Tests pass but need updating to cover new functionality, and re-enable AutoCompleteService test once there is a ServiceDiscovery component that registers and returns services. This is necessary as .Instance won't allow for dependency injection and proper testing.
