    ipatests: in DNS zone file add A record for name server
    
    Testcase test_server_option_with_unreachable_ad creates a zone file
    for AD domain. This file had a hard-coded A record for host specified in
    NS record. Some versions of BIND consider this zone invalid and refuse
    to start with message:
    ```
    zone ad.test/IN: NS 'root-dc.ad.test' has no address records (A or AAAA)
    ```
    
    Fixed by replacing hard-coded value with short name of the AD instance.
