dpdk: add intf tag to dev{} subinput
This patch allows to pass a tag when specifying the dpdk `dev { }` interface configuration. It allows a control plane generating a vpp.conf file to retreive the resulting mapping between dpdk interfaces & sw_if_indices in VPP without having to change the interface name exposed to the user.
