This patch moves PortBindingPort model under neutron/db/models for consistency.There are no plans to implement an OVO object for the model at this point in time. Actually, the model should probably eventually go away from Neutron tree since it's not used by reference plugin, and is just a remnant from the times when the neutron tree contained lots of plugins, some of which were using the model.
