CONTROLLER-1382 marked opendaylight-inventory model as deprecated, pending its removal in favor of ietf-topology. This work has been suspended until ietf-topology was standardized, which happened with RFC8345.

The standard model is ietf-network, which contains the baseline for building up a network inventory (without links which were previously part of ietf-topology).

We now need to finish this migration, which is mostly about OpenFlow Plugin and its downstreams. This will affect our NBI and needs come care, as ietf-network is a more general model – instead of relying on opendaylight-inventory's singular instantiation, OpenFlow world needs to be migrated to an instance of ietf-network – for example with network-id=openflow-inventory.
