What this PR does
Adds
antiPreemptibleAffinityconfig option to help for elasticsearch and postgres. Pods that have this affinity set will avoid being scheduled on preemptible pods whenever possible.I've also added a single non-preemptible node to the dev cluster and made the dev config use this value. So hopefully this means less up-and-down for our statefulsets in dev. Preview statefulsets will continue to be on preemptible infrastructure.
