[ONOS-7624] Implement egress pipeline programming
- Implemented logic to handle double-tagged host in segmentrouting application.
- Added 'DummyVlanId' to segmentrouting application to keep track of dummy vlan for L3L2Unfiltered group chain and egress tables.
- Implemented L2Unfiltered group and Egress pipeline programming support in OFDPA pipeline.
- Added EGRESS flag to the forwardingObjective to program Egress tables.
- Fixed bugs when handling double-tagged ARP request, to get correct vlan id and reply with double-tagged packet.
- Fixed bugs in BasicHostConfig, to set the value of 'outerTpid' to 0x8100 if it is not specified.
- Fixed build(ARP/ICMP/ICMP6)reply to build double-tagged reply if corresponding request is double-tagged.
