Description
Moved from https://github.com/StackStorm/st2enterprise-dockerfiles/issues/48
Currently we install single-node etcd instance as st2 [coordination] backend, just to get started quick.
Enhance the K8s manifests to configure 3 node HA cluster by default.
In future, further template with Helm to optionally use 5, 7 or more nodes, if user needs it.
Use 3rd party Helm chart for configuring etcd similar to mongodb-ha and rabbitmq-ha, instead of using quick hacked K8s objects.
