T7181: VPP Static and dynamic NAT

New CLI for static and dynamic NAT:
```
set vpp nat44 interface outside <interface>                     # multi
set vpp nat44 interface inside <interface>                      # multi
set vpp nat44 address-pool translation interface <interface>    # multi
set vpp nat44 address-pool translation address <address>        # multi
set vpp nat44 address-pool twice-nat interface <interface>      # multi
set vpp nat44 address-pool twice-nat address <address>                  # multi

set vpp nat44 static rule <rule> external address <address>
set vpp nat44 static rule <rule> external port <port>
set vpp nat44 static rule <rule> local address <address>
set vpp nat44 static rule <rule> local port <port>
set vpp nat44 static rule <rule> protocol <protocol>
set vpp nat44 static rule <rule> options twice-nat
set vpp nat44 static rule <rule> options self-twice-nat
set vpp nat44 static rule <rule> options out-to-in-only
set vpp nat44 static rule <rule> options twice-nat-address <address>

set vpp nat44 exclude rule <rule> protocol <protocol>
set vpp nat44 exclude rule <rule> local-port <port>
set vpp nat44 exclude rule <rule> local-address <address>
set vpp nat44 exclude rule <rule> external-interface <interface>
```
Settings:
```
set vpp settings nat44 session-limit <limit>            # default 64512
