Currently the best way to see what the evaluator choices are is to run a command like this:

$ cargo run -- configuration create --evaluators x --url http://whatever.com --configuration-name test --configuration-name-pretty test

Error: Configuration failed validation

Caused by:

    1: The given evaluator identifiers were unexpected: {"x"}

This is clearly a bit of a hack, it'd be good to have a bespoke subcommand for this.
