cgnat test case added
A cgnat test can now be executed. This test needs 3 PROX instances. The first one, the generator needs to have an interface on the private dataplane network. The second instance, the cgnat needs to have it's first dataplane interface on the private network, while the second data plane needs to be on the public network. The third instance will be playing the role of internet server that the generator is connecting to. It will have one dataplane interface on the public network. This third instance will increase the packet size of the received packets by padding it with zeros and it will send the packets back to the cgnat mutliple times. How many times is defined by a multiplier in the cgnat.cfg file. In that cgnat file, we also define a range of IP addresses that will be used for the dynamic source IP NAT-ing. Make sure that the ports are allowed to accept other IP addresses than their own (e.g. allowed address pairs) and that the range of IP addresses is not overlapping with other machines in the public network.
