adding a single syslog-ng configuration

I have put together these syslog-ng configuration files. It worked on CentOS
and should work on ubuntu as well. Perhaps get an alert due to 3.2 version in
place when starting up. As the system activity grows, one will need to tweak
syslog-ng settings to make sure it's handling swift logging properly and not
loosing any logs.
forgot to fix internal option
