Elastic Agent in ECK has no option to output to Logstash created by ECK.

Allow ECK deployed Elastic Agents to output to a Logstash Ref

I'm trying to configure my Elastic Agents to output to Logstash so that I can do some logstashy things before sending the data to Elasticsearch as well as some other locations.

I can't figure out how to configure the Elastic Agent CRD to reference the output to a Logstash instance deployed by ECK.
