@KalmanMeth can you add documentation for this.

Actually should config.Opt.PipeLine.Encode.Type be part of the API now ??? I think it should and than each of the encode options should be part of enum

I changed the name of the files to encode_json_to_string. The input is json (configMap), but the difference is that it outputs a string for each configMap. There is no API detail needed since there are no parameters that the user needs to provide.

In light of our discussion, I changed the name back to encode_json.go.
I also added a few sentences in the README to document the json encoder.
