title: Change log file name in logger module globally
body: <p>I'm using logger module with dictConfig (with a yaml file) for my application logging. However, I would to change the log file name globally by adding a date prefix (ex: logpath: /foo/bar/file_20150523.log). </p>
  
  <p>So each time I start my application a new log file is created.</p>
  
  <p>Is it possible in one way of another to do it inside the yaml file or I need to modify the handler in my application ?</p>
  
  <p>Thanx</p>
