This change restructures a lot more pertaining to deployments, snapshots, environments, and the like. The most notable change is that the notion of a deploy.Source is introduced, which splits the responsibility between the deploy.Plan -- which simply understands how to compute and carry out deployment plans -- and the idea of something that can produce new objects on-demand during deployment. The primary such implementation is evalSource, which encapsulates an interpreter and takes a package, args, and config map, and proceeds to run the interpreter in a distinct goroutine. It synchronizes as needed to poke and prod the interpreter along its path to create new resource objects. There are two other sources, however. First, a nullSource, which simply refuses to create new objects. This can be handy when writing isolated tests but is also used to simulate the "empty" environment as necessary to do a complete teardown of the target environment. Second, a fixedSource, which takes a pre-computed array of objects, and hands those, in order, to the planning engine; this is mostly useful as a testing technique. Boatloads of code is now changed and updated in the various CLI commands. This further chugs along towards pulumi/lumi#90. The end is in sight.
