      Previously, the ordering of NICs in the cloud provider was non-deterministic and could result in the node choosing the wrong NIC for communication with the cluster. This change updates the ordering to always be consistent, thus removing the possibility for random ordering making the node networking fail.

      Description of problem:

      nodeip-configuration.service is disabled to start during system startup on RHCOS on OCP cluster nodes on AWS. Because of this kubelet is picking a wrong node-ip when the OCP node on AWS has two IP addresses assigned to two interfaces. 

$ grep nodeip-configuration.service sos_commands/systemd/systemctl_list-unit-files nodeip-configuration.service                                                         disabled        disabledCluster Version

      Version-Release number of selected component (if applicable):

          4.14

      How reproducible:

      - Install a 4.14 cluster on AWS 
- Login to any node and check that nodeip-configuration.service will be found disabled for system startup.
