vCGNAPT VNF initial check-in

JIRA: SAMPLEVNF-5

The vCGNAPT implementation contains following features:
• Static and dynamic Network address translation.
• Static and dynamic Network address and port translation
• ARP (request, response, gratuitous)
• ICMP (terminal echo, echo response, pass-through)
• ICMPv6 and ND
• UDP, TCP and ICMP protocol pass-through
• Multithread support and Multiple physical port support
• Limiting max ports per client
• Limiting max clients per public IP address
• Live Session tracking to NAT flow
• NAT64 – connectivity between IPv6 access network to IPv4 data
• PCP - Port Control protocol
• SIP functionality
• FTP functionality
