app/testpmd: add protocol fields to flow command

This commit exposes the following item fields through the flow command: - VLAN priority code point, drop eligible indicator and VLAN identifier (all part of TCI). - IPv4 type of service, time to live and protocol. - IPv6 traffic class, flow label, next header and hop limit. - SCTP tag and checksum.
