EgressIP configuration at Openshift cluster hosted on AWS failing due to missing annotation

Issue

• EgressIP is not being assigned to the primary interface of the node as per hostsubnet definition.

• cloud.network.openshift.io/egress-ipconfig annotation is missing from the Node resource and that is causing problems while cloud-network-config-controller is trying to assign Egress IP to the primary interface of the node.
