Title:
  VMWare instance missing ip address when using config drive

Status in OpenStack Compute (nova):
  Fix Released
Status in OpenStack Compute (nova) kilo series:
  Fix Released

Bug description:
  Having same reason with race bug: https://bugs.launchpad.net/nova/+bug/1249065

  when vmware driver using config drive, the IP address maybe not get
  injected, because of the missing of instance nw_info cache.

  Here is related code in nova vmware driver, and config drive codes:

  https://github.com/openstack/nova/blob/master/nova/virt/vmwareapi/vmops.py#L671
          inst_md = instance_metadata.InstanceMetadata(instance,
                                                       content=injected_files,
                                                       extra_md=extra_md)

  https://github.com/openstack/nova/blob/master/nova/api/metadata/base.py#L146
          # get network info, and the rendered network template
          if network_info is None:
              network_info = instance.info_cache.network_info

  in vmwareapi/vmop.py, the network_info is not passed to the instance metadata api, so metadata api will use instance.info_cache.network_info as the network info. But when instance.info_cache.network_info is missing, the network info will be empty, too.
  This is why sometimes, VMWare instances can not get IP address injected when using config drive.
