Rewrite the SPGW P4 pipeline.
This commit makes two changes to the fabric.p4 source files:
1. Routing is now done on a metadata field instead of the ipv4 header.
Routing on the ipv4 header is incorrect if the packet is encapsulated
with an outer IPV4 header. The metadata field is updated each time the
ipv4 destination changes, or an outer header is added or removed. These
changes require no control plane modifications due to @name annotations.
2. The spgw control blocks have been rewritten to support the logical UP4
(cherry picked from commit bec6b6a7b0f33812c6f6904d9f9b629539446e79)

Case 1: DHCP v4 tests with 4 clients attached to switch directly and 1 server attached to switch directly, with 3 ONOS instances - FAIL
