Summary of Changes:

• The KafkaDriver class, which follows the Driver interface, has been created.
• The KafkaProcessorCommand console command has been added for processing tasks from Kafka.
• The createKafkaDriver method has been added to the ConcurrencyManager.
• The ConcurrencyServiceProvider has been updated to register the new command.
• Necessary tests for KafkaDriver have been written.

Important Notes for Usage:

• The PHP rdkafka extension must be installed.
• Before use, you need to run the php artisan concurrency:kafka-processor command to process the tasks.
• Kafka settings (servers, topics) can be configured in the concurrency.php config file.
