Title:
  delete an shelved_offloaded server cause failure in cinder

Status in OpenStack Compute (nova):
  Expired

Bug description:
  When deleting an shelved_offloaded STATE VM instance with volume
  attached, nova passes a connector dictionary:

    connector = {'ip': '127.0.0.1', 'initiator': 'iqn.fake'}

  to cinder for terminate connnection, this causes KeyError in cinder driver
  code :
  https://github.com/openstack/nova/blame/master/nova/compute/api.py#L1803

      def _local_cleanup_bdm_volumes(self, bdms, instance, context):
  1804	        """The method deletes the bdm records and, if a bdm is a volume, call
  1805	        the terminate connection and the detach volume via the Volume API.
  1806	        Note that at this point we do not have the information about the
  1807	        correct connector so we pass a fake one.
  1808	        """
  1809	        elevated = context.elevated()
  1810	        for bdm in bdms:
  1811	            if bdm.is_volume:
  1812	                # NOTE(vish): We don't have access to correct volume
  1813	                #             connector info, so just pass a fake
  1814	                #             connector. This can be improved when we
  1815	                #             expose get_volume_connector to rpc.
  1816	                connector = {'ip': '127.0.0.1', 'initiator': 'iqn.fake'}
  1817	                try:
  1818	                    self.volume_api.terminate_connection(context,
  1819	                                                         bdm.volume_id,
  1820	                                                         connector)
  1821	                    self.volume_api.detach(elevated, bdm.volume_id,
  1822	                                           instance.uuid)
  1823	                    if bdm.delete_on_termination:
  1824	                        self.volume_api.delete(context, bdm.volume_id)
  1825	                except Exception as exc:
  1826	                    err_str = _LW("Ignoring volume cleanup failure due to %s")
  1827	                    LOG.warn(err_str % exc, instance=instance)
  1828	            bdm.destroy()
  1829
  https://github.com/openstack/nova/blame/master/nova/compute/api.py#L1828

  according to my debug, the connector info for terminate_connection is
  already there( in bdm object):

  so Nova should build correct connection info for terminate_connection.

  ======Steps to reproduce

  1. create a server: nova boot ----
  2. shelve the server: nova shelve <server_id>
  3. delete the server: nova delete <server_id>
