Kafka 4.0 is expected to use Log4j2 for logging. We need to be able to deal with it. Assuming one or more Strimzi versions also support Kafka 3.9 and 4.0 in parallel, we might need to be able to support both Log4j1 for 3.9 and Log4j2 for 4.0.

Another thing for consideration is that Log4j2 supports periodic reloading. Do we want to keep updating logging through the Kafka APIs / rolling? Do we wanna relay on Log4j2 monitoring interval? That has to be decided.
