Now we need to explicitly create traffic_rule name before adding entities into it

It would be more convenient to create it automatically

sudo fcli set traffic_rule udp_ttl_62 ttls 62

set command returned error: Entity udp_ttl_62 does not exist

pavel@pavel:~$ sudo fcli set traffic_rule udp_ttl_62

Correctly created new rule with name udp_ttl_62

pavel@pavel:~$ sudo fcli set traffic_rule udp_ttl_62 ttls 62

Configuration updated correctly
