Add tolerations with effect "NoExecute" and "NoSchedule" to allow schedule of nodelocaldns pods on node pools with taints

Browse Source 
Currently if we define taints on all node pools in a cluster then nodelocaldns pods wont get scheduled on those node pools. Also in GKE as the daemonset has reconcile flag set tolerations cannot be added. So adding these tolerations will allow nodelocaldns pods to get scheduled on all node pools.
