title: How to config flask app.logger from a configure file?
body: <p>Is there any way to config flask app.logger from a configure file, like:</p>
  
  <pre><code>logging.config.fileConfig('/path/to/logging.cfg')
  </code></pre>
  
  <p>or </p>
  
  <pre><code>logging.config.dictConfig(config_dict)
  </code></pre>
  
  <p>So i can use <code>app.logger.info('some message')</code> to log both in develop and product mode.</p>
