docs: Configures LoggerWrapper to use only DailyRollingFileHandler.
  The supplied configuration options may contain the following properties:
  <ul>
  <li><code>ru.dmerkushov.loghelper.SizeRollingFileHandler.pattern</code> set to the desired DailyRollingFileHandler log file name pattern.</li>
  </ul>
  If the configuration options do not contain any of the options, SizeRollingFileHandler's default are used.
  
  @return always <code>true</code> (means the call is ever succesful)
