[RHOCP 4.x] openshift-dns daemonset doesn't include toleration to run on nodes with taints.

Issue

• Openshift-dns daemonset doesn't include toleration to run on nodes with taints. After a NoSchedule taint is configured for a node, the daemonset stops managing the pods on that node and 2 things happen:
• If the pods are deleted on nodes with taint, they won't be recovered.
• In OCP 4.9, alerts are shown in the OCP dashboard: Pods of DaemonSet openshift-dns/dns-default are running where they are not supposed to run.
