Tested on latest 4.5.0-0.ci release:

```
$ oc get ds --namespace openshift-machine-config-operator machine-config-daemon -o=jsonpath='{.spec.template.spec.tolerations}'
[map[operator:Exists]]

$ oc adm taint node ip-10-0-170-96.us-west-2.compute.internal infra=reserved:NoExecute
node/ip-10-0-170-96.us-west-2.compute.internal tainted

$ oc get pods --namespace openshift-machine-config-operator --field-selector spec.nodeName=ip-10-0-170-96.us-west-2.compute.internal
