Deprecation of http-logging filter

- Updates to the log4j settings for the repose-valve container to allow for slf4j to replicate the functionality of the http-logging filter.  
- Allow for more configuration around syslog facilities and what should be sent to syslog.  
- Allowing for different appenders for the local files to allow for size rotation as well as being able to use the NullAppender instead of the current DailyRollingFileAppender
