Phase 2 of the consul VM->k8s migration: terraform backends, the Vault
consul secret engine, and puppet all need the consul HTTP API reachable at
consul.k8s.syd1.au.unkin.net. The Gateway/HTTPRoutes currently send both
that hostname and the consul.service.consul listener to consul-ui:80,
which serves only the UI, not the /v1 API. Consul serves the HTTP API and
the UI (/ui/) on the same port 8500, so routing everything to 8500
preserves the UI while exposing the API.
- Add a consul-http ClusterIP service selecting the consul server pods
(app=consul, component=server, release=consul) on port 8500.
- Repoint the consul and consul-svc HTTPRoutes from consul-ui:80 to
consul-http:8500.
