nat: Final NAT44 EI/ED split patch
This patch achieves complete separation of endpoint-dependent and endpoint-independent IPv4 NAT features. Some common stuff is also moved to NAT library. Type: refactor Change-Id: I52468b7e2b5ac28958a2baf8e2ea01787322e801 Signed-off-by: Filip Varga <fivarga@cisco.com>
