> This is necessary for SSL/TLS support for inter-broker communication as `SimpleConsumer` will not be updated to support SSL/TLS.
> As explained by [~junrao] in KAFKA-2411: we need to be a bit careful since the follower fetcher thread doesn't need to refresh metadata itself. Instead, the information about the leader is propagated from the controller.
> This work was originally described in KAFKA-2411, which was then updated to be more narrowly focused on replacing `BlockingChannel` with `Selector`.
