Configure maxFileSize and maxBackupIndex with DailyRollingFileAppender.

Issue

• We're running fuse 6.3.0 with a fabric and want to fuse.log to rotate on a daily basis. I have configured org.ops4j.pax.logging.cfg based on documentation https://access.redhat.com/solutions/1146033. We've noticed logs rotate only is the log has been updated/written to. Is that the expected behavior?

• Also, according to the documentation I see both settings bellow are not included in the configuration when configured for daily log rotation. Can either or both settings below be used in conjunction with log4j.appender.out=org.apache.log4j.DailyRollingFileAppender configuration? In other words can log retention be configured along with daily log rotations?

log4j.appender.out.maxFileSize=100MB
log4j.appender.out.maxBackupIndex=30

• Here's my configuration...
