+++ This bug was initially created as a clone of Bug #1743160 +++

Description of problem:
when create a kubeletconfig, there will generate a relevant machineconfig whose ownerReferences kind should be "KubeletConfig". But now ownerReferences kind shows "ContainerRuntimeConfig"


Version-Release number of selected component (if applicable):
# oc version 
oc v4.0.0-alpha.0+1cdd4a1-781
kubernetes v1.11.0+1cdd4a1
Server https://api.qe-aws-411.qe.devcluster.openshift.com:6443
kubernetes v1.13.4+4715f6e

#oc get clusterversion

How reproducible:
always

Steps to Reproduce:
1.$ oc label machineconfigpool worker custom-kubelet=sysctl

2.$ cat custom-kubelet.yaml 
apiVersion: machineconfiguration.openshift.io/v1
kind: KubeletConfig
metadata:

  kubeletConfig:
    allowedUnsafeSysctls:
      - "kernel.msg*"
      - "net.ipv4.route.min_pmtu"

$ oc create -f custom-kubelet.yaml

3.$ oc get kubeletconfig  custom-kubelet -o yaml

Actual results:
in step 4, metadata-->ownerReferences-->kind show "ContainerRuntimeConfig"

Expected results:
in step 4, metadata-->ownerReferences-->kind show "KubeletConfig"

I've been testing this on 4.2 and can't reproduce the issue. Is this reproducible with 4.2 or above?
