Previously, the external network carried both public API traffic and
neutron external network traffic. In some cases is it useful to separate
these networks. The public network now carries the public API traffic,
leaving the external network to carry neutron external network traffic
alone. For backwards compatibility, the public network defaults to the
external network.
The oob_oc_network provides access to the out-of-band management controllers
of the overcloud hosts. The oob_wl_network provides access to the out-of-band
management controllers of the baremetal compute hosts.
