Ironic ports and portgroups correspond to the physical NICs that are available
on baremetal nodes. Neutron ports are logical ports attached to tenant and
provider networks. When booting baremetal nodes that have multiple ports or
portgroups, the mapping between logical and physical ports must account for
physical network connectivity of the system.

This feature aims to make Ironic aware of the 'physical_network' attribute of Neutron networks and network segments.
