Currently, there are some unit tests that are failing on Windows due to various reasons: - getHostDNSConfig is reading a resolv.conf file. However, we don't have that on Windows. Instead, we can get the DNS server list and the DNS suffix list from Windows itself. On Windows, getHostDNSConfig will now return the host's DNS configuration if the given resolverConfig is "Host". If it's not "Host" or an empty string, an error will be returned. Based on the code from kubernetes/test/images/agnhost/dns/dns_windows.go
