title: Logback, set max history files per day
body: <p>I use <code>TimeBasedRollingPolicy</code> and <code>SizeAndTimeBasedFNATP</code> triggering policy for my logback configuration. The rollover of log files is set to happen every day and it will also be triggered if log file size goes beyond a limit. </p>
  
  <p>If I do setMaxHistory(10) on <code>TimeBasedRollingPolicy</code> with a daily roll over, then it will archive all log files in last 10 days. But what I want is to set maxHIstory on SizeAndTimeBasedFNATP each day. </p>
  
  <p>Is this possible with logback?</p>
