Let Puppet serve up Lumberjack input plugin PKI files to logstash

Basically I wanted to roll out the logstash server, but saw no way within the module to do that. This places the 2 PKI files in /etc/logstash/lumberjack with the minimal amount of changes I could make to do it. I have tested that it works. 

Please tell me if I've done something wrong or got permissions wrong or similar, and I will change them and make another request.
