      * Previously, when you switched your cluster to use a different load balancer, the Ingress Operator did not remove the values from the `classicLoadBalancer` and `networkLoadBalancer` parameters in the `IngressController` custom resource (CR) status. This situation caused the status of the CR to report wrong information from the `classicLoadBalancer` and `networkLoadBalancer` parameters. With this release, after you switch your cluster to use a different load balancer, the Ingress Operator removes values from these parameters so that the CR reports a more accurate and less confusing message status.

      This is a clone of issue OCPBUGS-38217. The following is the description of the original issue:
      —
      Description of problem:

          After changing LB type from CLB to NLB, the "status.endpointPublishingStrategy.loadBalancer.providerParameters.aws.classicLoadBalancer" is still there, but if create new NLB ingresscontroller the "classicLoadBalancer" will not appear.

// after changing default ingresscontroller to NLB
$ oc -n openshift-ingress-operator get ingresscontroller/default -oyaml | yq .status.endpointPublishingStrategy.loadBalancer.providerParameters.aws
classicLoadBalancer:                   <<<< 
  connectionIdleTimeout: 0s            <<<<
networkLoadBalancer: {}
type: NLB

// create new ingresscontroller with NLB
$ oc -n openshift-ingress-operator get ingresscontroller/nlb -oyaml | yq .status.endpointPublishingStrategy.loadBalancer.providerParameters.aws
networkLoadBalancer: {}
type: NLB

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

          4.17.0-0.nightly-2024-08-08-013133

      How reproducible:

          100%

      Steps to Reproduce:

          1. changing default ingresscontroller to NLB
$ oc -n openshift-ingress-operator patch ingresscontroller/default --type=merge --patch='{"spec":{"endpointPublishingStrategy":{"type":"LoadBalancerService","loadBalancer":{"providerParameters":{"type":"AWS","aws":{"type":"NLB"}},"scope":"External"}}}}'

    2. create new ingresscontroller with NLB
kind: IngressController
apiVersion: operator.openshift.io/v1
metadata:
  name: nlb
  namespace: openshift-ingress-operator
spec:
  domain: nlb.<base-domain>
  replicas: 1
  endpointPublishingStrategy:
    loadBalancer:
      providerParameters:
        aws:
          type: NLB
        type: AWS
      scope: External
    type: LoadBalancerService

    3. check both ingresscontrollers status

      Actual results:

      // after changing default ingresscontroller to NLB 
$ oc -n openshift-ingress-operator get ingresscontroller/default -oyaml | yq .status.endpointPublishingStrategy.loadBalancer.providerParameters.aws
classicLoadBalancer:
  connectionIdleTimeout: 0s
networkLoadBalancer: {}
type: NLB
 
// new ingresscontroller with NLB
$ oc -n openshift-ingress-operator get ingresscontroller/nlb -oyaml | yq .status.endpointPublishingStrategy.loadBalancer.providerParameters.aws
networkLoadBalancer: {}
type: NLB

      Expected results:

          If type=NLB, then "classicLoadBalancer" should not appear in the status. and the status part should keep consistent whatever changing ingresscontroller to NLB or creating new one with NLB.
