NIFI-4378: Allow suppression of null values in JSON
----
> JSON Record Writer should allow user to suppress null values
> ------------------------------------------------------------

> Key: NIFI-4378
> URL: https://issues.apache.org/jira/browse/NIFI-4378
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Mark Payne

>
> When using the JSON Record Writer, it would be nice to be able to suppress
> null values. Ideally, we would be able to choose between 'Always Suppress',
> 'Never Suppress', and 'Suppress When Missing'. The 'Suppress When Missing'
> option would not write out a null field if the field had no value but would
> still write out a null if the value of the field were explicitly set to null.
> This allows for a differentiation between 'null' and a missing value.
