Title:
  Cells Response serialization was incorrect for NovaObjects

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  In nova.cells.messaging.Response, the serialization/deserialization
  was done using the oslo.serialization library which is not correctly
  serializing a NovaObject because it will loose all related attributes
  about versioning and classes. Consequently, when deserializing, it
  will be rehydrated into a dict instead of a NovaObject.

  http://git.openstack.org/cgit/openstack/nova/tree/nova/cells/messaging.py?id=9c45ff348d7eb75ae8098b6c950db549aaff282a#n1852

  
  The fix is easy and should call objects_base.serialize_entity() instead.
