Should we consider a dual client in the same project similar to the
approach in
https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-elasticsearch-bundle/nifi-elasticsearch-5-processors/src/main/java/org/apache/nifi/processors/elasticsearch/AbstractElasticsearch5TransportClientProcessor.java
?
We can then switch based on the presence of the es.xpack.user setting in
the ambari.---
