No predefined configuration for cluster mode in helm chart

A problem description The default configuration didn't fit for the production purposes because on high payload it gets timeout. At this point we tried to create HPA that also didn't help because the instances doesn't balancing the requests and still got timeout. Next thing we wanted to try is cluster mode, but we didn't find a solution to configure cluster mode with helm chart because there is no values for that.

Describe the solution you'd like Helm chart values for scalable solution
