Fix gtw address dynamic assignment

Currently address for gtw01 node is not assigned dynamically,
because it is overriden by _param:openstack_gateway_address,
and reclassify tool is setting openstack_gateway_node01_address,
as the result gtw01 gets ip not from reclassify but from model.
This causes duplication of this ip with nodes which got ip from
reclassify.
