feat(rollback): Support rolling back to a server group that no longer…
… exists (#1716) This PR provides a rollback strategy that will clone forward with the image details that were tagged as part of #1705. It also supports the `imageName` being explicitly provided, but that's an exceptional case that would not be supported in the UI. The `spinnaker:metadata` tag will include `buildInfo` for the image if it is returned from `clouddriver`.
