Replace the Source-based implementation of refresh with a phase that runs as the first part of plan execution and rewrites the snapshot in-memory. In order to fit neatly within the existing framework for resource operations, these changes introduce a new kind of step, RefreshStep, to represent refreshes. RefreshSteps operate similar to ReadSteps but do not imply that the resource being read is not managed by Pulumi. In addition to the refresh reimplementation, these changes incorporate those from #1394 to run refresh in the integration test framework. Fixes #1598. Fixes pulumi/pulumi-terraform#165. Contributes to #1449.
