Get rid of JSON.parse

[jwalton]

If you do this:

var logger = bunyan.createLogger({
  name: "My Application",
  streams: [
    { stream: process.stdout },
    { stream: esStream, type: 'raw' }
  ],
  serializers: bunyan.stdSerializers
});

Then bunyan will send you raw JSON objects instead of sending you strings, so you won't have to call JSON.parse() on the log entry that Bunyan just JSON.stringified().
