PMK-6377 Changing labels for hostplumber

[vedantjoshi84]

PMK-6377

Summary: luigi and hostplumber both had label controller-manger, when we delete network plugin it uses controller-manger label to pass request to webhook, since luigi and hostplumber both have same labels request gets forwarded to sometimes host plumber pod and sometimes luigi pod, which causes timeouts. So, changing the label for hostplumber.

Testing: Used image with my changes:

root@test-pf9-qbert-bare-os-u20-3262280-171-2:~# k describe pod -n luigi-system             luigi-controller-manager-6f84b6588-w5wbn
Name:             luigi-controller-manager-6f84b6588-w5wbn
Namespace:        luigi-system
...
Container ID:  containerd://03f75a75ffb090b5e825e9b691099b00cbcf5804a0f2782ba6452db30cda820a
    Image:         vedantjoshi84/luigi:v0.5.5-2

Then applied this network-plugin yaml:

root@test-pf9-qbert-bare-os-u20-3262280-171-2:~# cat luigi.yaml 
apiVersion: plumber.k8s.pf9.io/v1
kind: NetworkPlugins
metadata:
 finalizers:
 - teardownPlugins
 generation: 2
 labels:
  app.kubernetes.io/instance: prod-networking
 name: networkplugins2-luigi
spec:
 # Add fields here
 #privateRegistryBase: "localhost:5100"
 plugins:
  dhcpController: {}
  ovs: {}
  hostPlumber: {}
  nodeFeatureDiscovery: {}
  multus: {}
  whereabouts: 
   namespace: default
   ipReconcilerSchedule: "* * * * *"
  #sriov: {}
  #ovs: {}

root@test-pf9-qbert-bare-os-u20-3262280-171-2:~# k apply -f luigi.yaml 
Warning: metadata.finalizers: "teardownPlugins": prefer a domain-qualified finalizer name to avoid accidental conflicts with other finalizer writers
networkplugins.plumber.k8s.pf9.io/networkplugins2-luigi created

Was able to delete it later on:

root@test-pf9-qbert-bare-os-u20-3262280-171-2:~# k delete networkplugins networkplugins2-luigi
networkplugins.plumber.k8s.pf9.io "networkplugins2-luigi" deleted

Label applied to the hostplumber pod:

apiVersion: v1
kind: Pod
metadata:
  annotations:
    kubectl.kubernetes.io/default-container: manager
  creationTimestamp: "2024-05-16T09:24:41Z"
  generateName: hostplumber-controller-manager-
  labels:
    control-plane: hostplumber-controller-manager
