Subject: T7390: VPP CGNAT implementation (#30)

CLI:
```
set vpp nat cgnat interface outside <interface>        # multi
set vpp nat cgnat interface inside <interface>         # multi

set vpp nat cgnat rule <rule> outside-prefix <prefix>
set vpp nat cgnat rule <rule> inside-prefix <prefix>

set vpp nat cgnat timeout udp <sec>                # default 300
set vpp nat cgnat timeout tcp-established <sec>    # default 7440
set vpp nat cgnat timeout tcp-transitory <sec>     # default 240
set vpp nat cgnat timeout icmp <sec>               # default 60
```
OP mode:
```
show vpp nat cgnat interfaces
show vpp nat cgnat mappings
show vpp nat cgnat sessions

clear vpp cgnat inside-address <address> port <port> external-address <address> port <port>
```
