Description of problem: While setting systemReserved/memory option using KubeletConfig object, and this option didn’t present in the generated kubelet machine config object.

The KubeletConfig they are using is:

~~~
[kni@sai-provisioner-cp-2 ~]$ oc get kubeletconfig -o yaml
apiVersion: v1
items:

• apiVersion: machineconfiguration.openshift.io/v1
  kind: KubeletConfig
  metadata:
  creationTimestamp: "2022-11-18T12:23:15Z"
  finalizers:
• 99-worker-generated-kubelet
• 99-master-generated-kubelet
  generation: 1
  name: custom-kubeletconfig
  resourceVersion: "563342"
  uid: 3a08ed33-79b3-4198-87ff-a835af75da07
  spec:
  kubeletConfig:
  cpuManagerPolicy: static
  cpuManagerReconcilePeriod: 5s
  systemReserved:
  memory: 2Gi
  machineConfigPoolSelector:
  matchLabels:
  machineconfiguration.openshift.io/mco-built-in: ""

and then machine config is
