When calling OSC commands "openstack baremetal node create" or
"openstack baremetal node show" the field "chassis_uuid" should be
displayed even if it is empty.
This patch also updated the test schema for the ironic --json node-*
command as chassis_uuid will now appear as 'null' when the node isn't
associated with a chassis.
