When a resource fails to initialize (i.e., it is successfully created, but fails to transition to a fully-initialized state), and a user subsequently runs `pulumi update` without changing that resource, our CLI will fail to warn the user that this resource is not initialized. This commit begins the process of allowing our CLI to report this by storing a list of initialization errors in the checkpoint.
