This change introduces a new ``HostPortProfileInfo`` class to model the supported port profiles of each os-vif VIF object. Nova will retrieve the host plugin information in ``HostInfo`` and will populate to Neutron when binding a new port. Neutron, with the list of supported VIF types along with the port info per plugin, will bind the port and return to Nova the corresponding os-vif VIF object. blueprint vif-port-profile Change-Id: Idb206576570f04a6403b933b83eebf9b0f06a91a
