Bug Description
In addition to nodeSelectors, Kubernetes supports tolerations and affinity / anti-affinity to influence scheduling pods to nodes. Tolerations in particular are important for setups where certain nodes should be reserved for system-level services and thus have taints on them to prevent scheduling normal pods, which can be selectively overridden by tolerations on the pod spec. We've already had at least one request to adjust tolerations for a cdk-addon which is currently being converted to a K8s charm.
