I'm deploying hazelcast on k8s using the helmchart on github currently on revision 5.3.2.

How would one go about running two clusters, say dev_cache and qa_cache in one helm deployment each with different members? Is that possible?

I see the fields

hazelcast:
   javaOptions:
     existingConfigMap: xxx

and

configurationFiles: #any additional Hazelcast configuration files

in the values.yaml but am unable to find any documentation on how to use them.
