[FEATURE] Create a Kafka Test Container based upon KoP

[david-streamlio]

Is your feature request related to a problem? Please describe.
Customers who are using the Quarkus development framework to develop Kafka applications use a Kafka Test Container from the Test Containers project for all of their unit and integration tests.

Customers would rather test against a KoP test container than a pure Kafka one as it would be closer to what their production environment would be.

Describe the solution you'd like
I would like it if we could use a different Docker image inside the existing KafkaTest container instead of the Confluent one, e.g.

KafkaContainer kafka = new KafkaContainer(DockerImageName.parse("confluentinc/cp-kafka:6.2.1"))

This would allow customers to swap out the confluent image for our KoP image and minimize the code changes required for migrating to KoP.

Describe alternatives you've considered
None

Additional context
I think such a container can be easily developed from the existing streamnative/sn-pulsar docker image that already contains the KoP protocol handler. We just need to add some configuration properties to enable it, e.g.,

`FROM streamnative/sn-pulsar:2.10.3.6

RUN echo "messagingProtocols=kafka" >> /pulsar/conf/standalone.conf &&
echo "protocolHandlerDirectory=./protocols" >> /pulsar/conf/standalone.conf &&
echo "allowAutoTopicCreationType=partitioned" >> /pulsar/conf/standalone.conf &&
echo "kafkaListeners=kafka_internal://0.0.0.0:9092" >> /pulsar/conf/standalone.conf &&
echo "kafkaProtocolMap=kafka_internal:PLAINTEXT" >> /pulsar/conf/standalone.conf &&
echo "kafkaAdvertisedListeners=kafka_internal://localhost:9092" >> /pulsar/conf/standalone.conf &&
echo "brokerEntryMetadataInterceptors=org.apache.pulsar.common.intercept.AppendIndexMetadataInterceptor" >> /pulsar/conf/standalone.conf &&
echo "brokerDeleteInactiveTopicsEnabled=false" >> /pulsar/conf/standalone.conf`
