Single-node Apache Kafka without Zookeeper using official docker image or say "No" to Zookeeper

As we know, since 3.7 the official Kafka image appeared.

Here is putted together config, based on the previous one.

Also having in mind necessary replication factor and ISR settings to have ability to run single node (by default you need to run 3 nodes).

Also having in mind that Kafka uses bootstrap mechanism which provides actual servers, so we need to declare them (PLAINTEXT_HOST in config below)
