This isn't easily tested with a unit test, so here's a flowfile that can be
tested against an ES instance running on localhost:9200 (ie defaults)
[Nullable_ES_Test.xml.txt](https://github.com/apache/nifi/files/1771209/Nullable_ES_Test.xml.txt)
> Suppress Nulls for PutElasticsearchHttpRecord

> Key: NIFI-4743
> URL: https://issues.apache.org/jira/browse/NIFI-4743
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Extensions

> Would be useful for PutElasticsearchHttpRecord to allow you to suppress NULL
> values in the JSON that is inserted into ES much like the JsonRecordSetWriter
> allows you to do. Perhaps PutElasticsearchHttpRecord could some how make use
> of JsonRecordSetWriter so it would inherit this functionality.
