JSONpath support

[Mihailoff]

How is it difficult to add JSON path support? There are cases when doted fqdn is just impossible to know upfront.

{  
  addField: {  
    config: {  
       jsonpath: "$..author"
       value: "replace"
    }
  }
}

@Mihailoff can you expand a bit about your use case? It would be useful to see a JSON document, and how you would expect the JSONPath processor to work.
