The Oslo Versioned Objects history is used to generate the manifests required to do compatibility changes to OVOs on data serialization between services running with different OVO history versions. We haven't updated our OVO history since Train so all the history and compatibility code (obj_make_compatible method) is no longer necessary. This patch consolidates the OVO history into a single version reflecting the current status of the OVO versions and removes the compatibility code from the OVO classes. Since we tend to forget to update the obj_make_compatible when we add a field (like it happened with Volume in version 1.8 when we added shared_targets) this patch also adds a note next to the "fields" attribute (except for the list OVOs which are never updated).
