These changes add the ability to export a stack's latest deployment or import a new deployment to a stack via the Pulumi CLI. These capabilities are exposed by two new verbs under `stack`: - export, which writes the current stack's latest deployment to stdout - import, which reads a new deployment from stdin and applies it to the current stack. In the local case, this simply involves reading/writing the stack's latest checkpoint file. In the cloud case, this involves hitting two new endpoints on the service to perform the export or import.
