Do we need beaver/logstash-forwarder?

I think we'll support the java agent to start and consider these other two later.

We need a logstash-agent, the java one provided by logstash is pretty cool performs quite well and have some many options (input/output/filters etc...) if we want something simpler without Java, then logstash-fowarder/beaver might be a good alternative
