Title:
  swap volume operation may leak credentials into debug logs

Status in OpenStack Compute (nova):
  In Progress
Status in OpenStack Security Advisory:
  Won't Fix

Bug description:
  The swap volume code in the compute service logs old and new volume
  connection_info dicts to debug here:

  https://github.com/openstack/nova/blob/1ad41c0b0c844b65424251dbc3399039789b064f/nova/compute/manager.py#L4930

  The new connection_info comes from Cinder:

  https://github.com/openstack/nova/blob/1ad41c0b0c844b65424251dbc3399039789b064f/nova/compute/manager.py#L4901

  That's a plain dict from the response which may contain credentials.

  The old connection_info comes from the
  nova.objects.block_device.BlockDeviceMapping object, which uses
  SensitiveStringField to sanitize the field's value when logged:

  https://github.com/openstack/nova/blob/1ad41c0b0c844b65424251dbc3399039789b064f/nova/compute/manager.py#L4904

  https://github.com/openstack/oslo.versionedobjects/blob/1.23.0/oslo_versionedobjects/fields.py#L280

  The new connection_info could contain credentials though, so we should
  mask those when logging it, even at debug level.
