The DnsManager was still checking for the old dnsDomain property that was
replaced by dnsNsDomains and dnsScopes in the DNS Architecture Improvements.
Changes:
- Replace dnsDomain checks with dnsNsDomains and dnsScopes validation
- Add check to ensure email domain is included in dnsScopes array
- Update NS delegation check to work with multiple nameservers
- Update error messages to guide users to the new configuration format
