Move Pod Topology Spread Constraints into scheduling

These constraints apply specifically to the mechanism for placing Pods
onto nodes (that is, scheduling).

 ### 1. Upgrade to kubernetes 1.18 and make use of Pod Topology Spread Constraints
 
 While this seems like it could have been the perfect solution, at the time of writing Kubernetes 1.18 was unavailable on the two most common managed Kubernetes services in public cloud, EKS and GKE.
-Furthermore, [pod topology spread constraints](/docs/concepts/workloads/pods/pod-topology-spread-constraints/) were still a [beta feature in 1.18](https://v1-18.docs.kubernetes.io/docs/concepts/workloads/pods/pod-topology-spread-constraints/) which meant that it [wasn't guaranteed to be available in managed clusters](https://cloud.google.com/kubernetes-engine/docs/concepts/types-of-clusters#kubernetes_feature_choices) even when v1.18 became available.
