title: Is it possible to log the progress during a webpack build?
body: <p>When I am running linting I get errors if something is wrong, otherwise I get no notification that the linting i executed. Is it possible to add logging messages after plugins or loaders are executed?</p>
  
  <p>In my particular case I would like to add log messages after the "StyleLintPlugin"-plugin and "tslint"-loader. See the Webpack config below.</p>
