Match existing kubelet-config`s in kubernetes-1.24

[arnaldo2792]

Issue number:

Closes #2538

Description of changes:

In #2437, we added support for kubernetes 1.24, but I missed the change introduced by #2436.

Testing done:

• I checked the default values for kubeAPIQPS and kubeAPIBurst were used when none were provided in the API
• I checked the configuration file was re-rendered when the API changed

# Default
bash-5.1# cat /etc/kubernetes/kubelet/config  | grep QPS
kubeAPIQPS: 10
# New value
bash-5.1# apiclient set kubernetes.kube-api-qps=20
bash-5.1# cat /etc/kubernetes/kubelet/config  | grep QPS
kubeAPIQPS: 20
# New value
bash-5.1# apiclient set kubernetes.kube-api-burst=30
bash-5.1# cat /etc/kubernetes/kubelet/config  | grep Burst
kubeAPIBurst: 30
