[PATCH 2/8] app/testpmd: add support for NAT64 in the command line

[Bing Zhao]

The type of NAT64 action will be parsed.

Usage example with template API:
  ...
  flow actions_template 0 create ingress actions_template_id 1 \
    template count / nat64 / jump / end mask count / nat64 / \
    jump / end
  flow template_table 0 create group 1 priority 0 ingress table_id \
    0x1 rules_number 8 pattern_template 0 actions_template 1
  flow queue 0 create 2 template_table 0x1 pattern_template 0 \
    actions_template 0 postpone no pattern eth / end actions count / \
    nat64 type 1 / jump group 2 / end
   ...
