Where did High Availability go?

[WillNilges]

Howdy, I was trying to adapt the minikube HA deployment to full K8s, and making great progress, but since that massive refactor, I seem to have lost track of where HA was being kept in this repo. Did you guys remove it? Why?

The documentation still says that it's an option, and so does the .env file in the base dir: https://thingsboard.io/docs/user-guide/install/cluster/minikube-cluster-setup/

Type ‘yes’ when prompted, if you are running ThingsBoard in high-availability DEPLOYMENT_TYPE for the first time or don’t have configured Redis cluster.

https://github.com/thingsboard/thingsboard-ce-k8s/blob/master/.env

# Can be either basic (with single instance of Zookeeper, Kafka and Redis) or high-availability (with Zookeeper, Kafka and Redis in cluster modes and PostgreSQL in replica mode if chosen).

I think it was removed here in this pr
