I don't know if the change server.1=nifi has an impact. I tested but I have no error.

It's only used for embedded zookeeper, so I don't think we'd see it in Kubernetes. I think it's probably okay. Anyone using this would need to override it to include each nifi node name anyway, so i don't think there's a risk. This can be merged with no risk.

@mh013370 I made a change to not use the template if not needed can you recheck?

Should we just remove the zookeeper properties template here like we removed the logback template in #353 ?
