JsonFormatter class

JsonFormatter is used to encode Record to JSON format.

Make sure that no fields with overlapping names are provided as formatter de-duplicates collapsing fields, i.e. providing fields with the same key results only to a single field is include into the output.

As such we strongly recommend not to put fields in to any collections fields with key such as level, message, name and timestamp.
