Also for pubsub trips back to CV1/CV2, rather than having 2 queues for each service (networks & members), theres now only a single queue for each change type, and `frontend = (cv1|cv2)` attribute is set on the message for filtering.
New config block in local.conf for controllers: ``` { "settings": { ...standard zt1 local.conf settings... }, "controller": { "listenMode": (pgsql|redis|pubsub), "statusMode": (pgsql|redis|bigtable), "redis": { "hostname": ..., "port": 6379, "clusterMode": true }, "pubsub": { "project_id": <gcp-project-id> }, "bigtable": { "project_id": <gcp-project-id>, "instance_id": <bigtable-instance-id>, "table_id": <bigtable-table-id> } } } ```
Still need to do the actual configuration from local.conf
