Add TCP keepalive #63
Description
Would it be possible to add support for TCP keepalive in the tcp_output plugin by default?
I found that the tcp input plugin supports keepalive
/usr/share/logstash/vendor/bundle/jruby/3.1.0/gems/logstash-input-tcp-6.4.6-java/lib/logstash/inputs/tcp.rb
However I need this on the output plugin
/usr/share/logstash/vendor/bundle/jruby/3.1.0/gems/logstash-output-tcp-6.2.2/lib/logstash/outputs/tcp.rb
Currently I am manually duplicating the keepalive settings from the tcp-input plugin over to the tcp-output plugin to enable this feature every time I update logstash. Would be nice if this were baked in so it could be easily turned on in the config.
