* Add `node_taints` variable to worker modules to set custom initial node taints on cloud platforms that support auto-scaling worker pools of heterogeneous nodes (i.e. AWS, Azure, GCP) * Worker pools could use custom `node_labels` to allowed workloads to select among differentiated nodes, while custom `node_taints` allows a worker pool's nodes to be tainted as special to prevent scheduling, except by workloads that explicitly tolerate the taint * Expose `daemonset_tolerations` in AWS, Azure, and GCP kubernetes cluster modules, to determine whether `kube-system` components should tolerate the custom taint (advanced use covered in docs) Rel: #550, #663 Closes #429
