Part of the bind rollout split. **Merge #219 (bind-operator) first** — stacked on it; diff reduces to the binddns-externaldns files once #219 merges. ## Why The external-dns tier (replaces 3x Puppet external-dns servers): an authoritative cluster whose zones accept RFC2136 TSIG updates from external-dns. ## Changes - `apps/base/binddns-externaldns`: authoritative `BindCluster` (3 replicas, LoadBalancer/PureLB), `BindTSIGKey` for RFC2136, namespace - au-syd1 `binddns-externaldns` overlay ## Deploy impact Creates the `binddns-externaldns` StatefulSet + LoadBalancer once merged.
