Option to disable SSU Peer Test

While working with Arctic I discovered that his firewall configuration actually changes the source port in outgoing datagrams to a random value. This breaks the current Alice → Bob → Charlie → Alice test because Bob forwards to Charlie the port that he sees, but that is open for responses only from Bob.

As a result after running the test the router decides that it's firewalled even though the appropriate ports are forwarded correctly and inbound unsolicited SSU sessions get established just fine.

As it would be too much work to redesign the peer test to cater to this rare type of firewall, I suggest we just add an option to disable the test altogether.

After more analysis, SSU links do not get established just fine, there are many problems with them. So this ticket is not useful. Closing.
