Title:
  Version change in ObjectField does not work with back-levelling

Status in OpenStack Compute (nova):
  In Progress
Status in oslo.versionedobjects:
  New

Bug description:
  When a NovaObject primitive is deserialized the object version is
  checked and an IncompatibleObjectVersion exception is raised if the
  serialized primitive is labelled with a version that is not known
  locally. The exception indicates what version is known locally, and
  the deserialization attempts to backport the primitive to the local
  version.

  If a NovaObject A has an ObjectField b containing NovaObject B and it
  is B that has the incompatible version, the version number in the
  exception will be the the locally supported version for B. The
  desrialization will then attempt to backport the primitive of object A
  to the locally supported version number for object B.
