Review comment:
I believe it would be easier to read and understand later on if you add the
CM service above to `serviceList` and modify `getRoles(rolesResourceApi,
clusterName, serviceName)` to fetch the roles using the CM REST API for other
services and add CM API/UI role manually. Then you would not have to copy-paste
the logic which checks service model generators
