Add a new backend plugin (backend-split-horizon-bind9) that configures two BIND9 instances with split-horizon views, enabling replication across pools and BINDs: - Default pool: "default" view on both BINDs, no TSIG key - Split-horizon pool: dedicated TSIG-protected view on both BINDs The plugin creates the TSIG key, registers it with Designate, and embeds the tsigkey_id in pools.yaml so the association survives designate-manage pool update cycles.
