KAFKA-18773: Migrate the log4j1 config to log4j 2 for native image and README (wip)

[FrankYang0529]

Test steps

1. Build release gzipped tar ball and use a local server to host it.

> ./gradlew clean releaseTarGz
> python -m http.server

2. In another terminal, create native image.

> cd docker
> python docker_build_test.py kafka/test --image-tag KAFKA-18773 --image-type native --kafka-url http://<your ip>:8000/core/build/distributions/kafka_2.13-4.1.0-SNAPSHOT.tgz --build

3. Run the container.

> docker run -p 9092:9092 --name kafka --rm kafka/test:KAFKA-18773
