This patch attempts to generalize server initialization for KIP-500. It adds a
Servertrait whichKafkaServerextends for the legacy Zookeeper server, and a newKafkaRaftServerfor the new server. I have also added stubs forKafkaRaftBrokerandKafkaRaftControllerto give a clearer idea how this will be used.This patch attempts to be non-intrusive, but it's worth pointing out that it does away with
KafkaServerStartable. I believe this was intended to support custom startup logic, but it is not an official API and we do not plan to support it after KIP-500.Committer Checklist (excluded from commit message)
