    Save updated-in-place resources to backup stack

    The patch changes the approach of resource backup during stack
    update. It stores the definition of resource that needs to be
    updated in-place to backup stack(if it was not created before).

    Without this functionality, InvalidTemplateReference will be thrown
    every time when update-replaced resource has a reference to updated
    in-place resource and stack update was failed. In this case, backup
    stack has a resource that refers to not-presented another resource
    and backup stack deletion generates an exception.
