when using an IDE or a REST API it can be handy to have a command that returns some result object that can be a blob of data that can be parsed/used by a program rather than textual console output.

e.g. return a blob of JSON from a REST GET/POST on a forge command.

We have a message a String which is great for textual status messages. But it might be nice to add an optional entity property which folks could access from an IDE or REST API
