NIFI-4853: Fixed PutMongoRecord handling of nested records
----
> PutMongoRecord doesn't handle nested records
> --------------------------------------------
>
> Key: NIFI-4853
> URL: https://issues.apache.org/jira/browse/NIFI-4853
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Reporter: Matt Burgess
> Assignee: Matt Burgess
> Priority: Major
>
> PutMongoRecord works well with flat records, but when attempting to put in
> nested records (records whose fields are arrays or records themselves), the
> Mongo serializer doesn't know how to handle the complex NiFi record field
> types (such as MapRecord).
> The fix is to traverse all fields in the record, transforming the fields (if
> necessary) to Java objects for use by the Mongo serializer(s). Something very
> similar was done for PutDruidRecord, and in fact there is a utility method
> DataTypeUtils.convertRecordFieldtoObject() that can perform this task.
