This change, part of pulumi/lumi#90, overhauls quite a bit of the core resource, planning, environments, and related areas. The biggest amount of movement comes from the splitting of pkg/resource into multiple sub-packages. This results in: - pkg/resource: just the core resource data structures. - pkg/resource/deployment: all planning and deployment logic. - pkg/resource/environment: all environment, configuration, and serialized checkpoint structures and logic. - pkg/resource/plugin: all dynamically loaded analyzer and provider logic, including the actual loading and RPC mechanisms. This also splits the resource abstraction up. We now have: - resource.Resource: a shared interface. - resource.Object: a resource that is connected to a live object that will periodically observe mutations due to ongoing evaluation of computations. Snapshots of its state may be taken; however, this is purely a "pre-planning" abstraction. - resource.State: a snapshot of a resource's state that is frozen. In other words, it is no longer connected to a live object. This is what will store provider outputs (ID and properties), and is what may be serialized into a deployment record. The branch is in a half-baked state as of this change; more changes are to come...
