Operator will update nameservers addr always. #120
Description
Sometimes, hostsIps are equal to instance.Status.NameServers, just the order of value is different. But reflect.DeepEqual will return false to this situation, so operator will update nameservices always.
For example, hostIps = ['192.168.2.1', '192.168.2.11'], instance.Status.NameServers = ['192.168.2.11', '192.168.2.1']
