[RHOCP 4] NMstate configuration is causing issue with IPAddress ordering on Egress Nodes

Issue

• Updating DNS using Kubernetes NMState results in changing the ordering of the IP addresses to alphanumerically sorted IP addresses on the Egress node.

• When Kubernetes NMState is configured for updating the DNS server, an issue is observed on Egress Nodes, the ordering of the IP Addresses changes, and Node IPs are sorted by alphanumeric order.

• For instance, consider 10.xx.xx.17 is the egress IP assigned to a node, and 10.xx.xx.2 is the actual host IP. In this case, 10.xx.xx.17 will take precedence over the host IP 10.xx.xx.2 if sorted alphanumerically. Ideally, the host IP should not change to an egress IP.
