Dynamic Listener configuration for Kubernetes deployment and fixing java core dumping for AMR64

[mmohamed]

• For ARM64 arch, switching base image from 'openjdk:8u212-jre-alpine' to 'openjdk:8u201-jre-alpine' to prevent container core dump @see issue.
• For K8S deployment, add a 'KAFKA_LISTENERS_COMMAND' environment parameter to build 'KAFKA_LISTENERS' on fly (to use pod hostname when container started) @see start_kafka.sh

if [[ -n "$KAFKA_LISTENERS_COMMAND" ]]; then
    KAFKA_LISTENERS=$(eval "$KAFKA_LISTENERS_COMMAND")
    export KAFKA_LISTENERS
    unset KAFKA_LISTENERS_COMMAND
fi
