While investigating T333922: toolforge k8s control plane freezing and other stability issues we noticed that the Toolforge Kubernetes coredns pods are using quite a bit of CPU on the control plane nodes. To spread out that load we want to increase the number of replicas either by hand or by implementing autoscaling (T239404).
