Add randomizens system test which ensures that NS are randomly selected. The test relies of the fact that `getaddresses_allowed()` logic won't allow to query more than 3 NS at the top-level. The `example.` zone has 4 NS and the 3 formers are lame. As a result, if the resolved doesn't randomize the NS selection, it will only quiery the 3 formers, which won't give an answer, and fails. With randomization enabled, there is a chance that the resolver queries the fourth NS, and gets the result. |
