In my environment I'm not allowed to have a cert dns name like barman-cloud. It must be barman-cloud.svc. This was addressed in cloudnative-pg/cloudnative-pg#9222 by adding a new annotation in the barman-cloud service: cnpg.io/pluginServerName

The plugin-barman-cloud chart does not allow us to change the dnsNames or add the new annotation to the service. I tried using the Values.service.name but that gives an error that service name is not a valid DNS-1035 label.
