This turned out to be a big messy commit, since the way providers are referenced is tightly coupled throughout the code. That starts to unify how providers are referenced, using the format output node Name method. Add a new field to the internal resource data types called ResolvedProvider. This is set by a new setter method SetProvider when a resource is connected to a provider during graph creation. This allows us to later lookup the provider instance a resource is connected to, without requiring it to have the same module path. The InitProvider context method now takes 2 arguments, one if the provider type and the second is the full name of the provider. While the provider type could still be parsed from the full name, this makes it more explicit and, and changes to the name format won't effect this code.
