Add logfile rotation variables to the telegraf config file

[jschoewe]

Pull Request (PR) description

This PR adds optional logfile rotation variables for the telegraf config file. Without these variables our log files are becoming too large and filling up the drive space on our backup servers

I've never used this CI tool before but I'm kind of confused because it's giving me syntax errors in files that I didn't touch. Should I fix those as well?

[bastelfreak]

that's currently failing because of an updated dependency. I tried to fix that in https://travis-ci.org/github/voxpupuli/puppet-telegraf/builds/714241007 (https://github.com/voxpupuli/puppet-telegraf/pull/147) but I'm not yet sure why the tests fail :(
