--quiet=true doesn't set config.quietMode to true

[asbjornu]

When passing --quiet=true to the command line, config.quietMode isn't set to true. I would like to extract the value of --quiet in some of my code to silence it in development mode. How do I achieve that?

// .eleventy.js
module.exports = function (config) {
  // always prints `false` regardless of what `--quiet` is set to.
  console.log(config.quietMode);
};

I can see from #808 and 727607c that isVerbose is being set, but that property doesn't seem to be exposed in the Eleventy configuration.
