Backport fabric-spgw TNA changes to v1model

This branch ports the SPGW pipeline of fabric-tna back to v1model to
make the tables and actions consistent across the two versions. This
consistency will allow for testing of ONOS apps on both software and
hardware targets, since the only available software target that works
with ONOS requires v1model p4 programs. Changes to the fabric testing
suite (fabric-p4test) will be pushed in parallel.
