Add a sample program to demostrate the possible usage of get_socket_cookie and get_socket_uid helper function. The program will store bytes and packets counting of in/out traffic monitored by iptables and store the stats in a bpf map in per socket base. The owner uid of the socket will be stored as part of the data entry. A shell script for running the program is also included.
