title: logfile endpoint in Spring Boot
body: <p>I read Spring Boot Actuator <a href="http://docs.spring.io/spring-boot/docs/current/reference/html/production-ready-endpoints.html#production-ready-customizing-endpoints" rel="noreferrer">documentation</a> and saw <code>logfile</code> endpoint mentioned there which would really come in handy.</p>
  
  <p>However this endpoint is not registered in my app and I have no idea how to make it available. What is needed here? </p>
