Title:
  Heal instance info cache causes high extra DB queries

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  _heal_instance_info_cache currently does not load system_metadata.  As
  a result, the calls into _get_instance_nw_info end up lazy loading the
  data via obj_load_attr() when checking for the presence of system
  metadata.
