This changes the resource model to persist input and output properties distinctly, so that when we diff changes, we only do so on the programmer- specified input properties. This eliminates problems when the outputs differ slightly; e.g., when the provider normalizes inputs, adds its own values, or fails to produce new values that match the inputs. This change simultaneously makes progress on pulumi/lumi#90, by beginning tracking the resource objects implicated in a computed property's value. I believe this fixes both #189 and #198.
