Create a convention for structured output across commands (i.e. JSON)

You might want to do a find for a filtered export followed by a load of the S3 content written. To do that you'll want to get the S3 location written to by find. Maybe we should have a way to process the output in a structured manner to enable this more easily.

The aws command has it:

       --output (string)
       The formatting style for command output.
       o json
       o text
       o table
       o yaml
       o yaml-stream
