Description

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.
