Question to the SchemaTransformer logic

Likewise @sachindshinde - not sure if the latest updates made under #101 allow this to be closed

Hello 👋

But in case if I just want to reference another type and I don't extend it with any additional attributes, why do I have to define data fetcher that will never be invoked?

This was addressed in Federation v2 -> if you just need to reference entity now you can specify resolvable: false on the @key directive. This will ensure that the router/gateway will not attempt to resolve the type in the given subgraph and always make federated call.

I've updated the logic in #285 to also auto populate _Entity union type resolver with a fake one (that throws runtime exception if invoked -> it should never be invoked, if for some reason it is, e.g. due to local testing, your provided resolver takes precedence) and no longer require _entities resolver if all entities are non-resolvable.
