Set resource reservations for kubelet and other system processes

Following our efforts to improve the overall stability of our Kubernetes clusters, we’ve now set resource reservations for kubelet and other system processes. This will ensure that these critical processes always have enough CPU and memory available to function properly, regardless of what the actual cluster workloads are.

These changes have already been rolled out to all staging clusters and, as usual, production clusters will follow next week if no issues are spotted.
