Dan Smith 93a3017999 Remove obj_relationships from objects
In Liberty, we converted to using the manifest-based class
action and backport methods, which no longer rely on these
object relationship maps. They provide a full manifest of
client-side versions with each call, which is far more
robust than us trying to hand-edit these mappings (which
we get incorrect a lot).

Since we're now in Mitaka, we can drop compatibility with
clients that don't make the version-manifest calls. Those
have also been deprecated in oslo.versionedobjects.
