Apache Kafka handler for Monolog

Support for logging into Apache Kafka using rdkafka extension.

Usage example:

$config = new \RdKafka\Conf();
$config->set('metadata.broker.list', '127.0.0.1');
$producer = new \RdKafka\Producer($config);
$logger = new Logger('my_logger');
$logger->pushHandler(new KafkaHandler($producer, 'test'));

Works with:

• PHP 7.4+ with PECL rdkafka 4.x/5.x
• PHP 8+ with PECL rdkafka 5.x

Manually tested with Apache Kafka 2.8.0.

If you need support for earlier versions of PHP or rdkafka extension, please check out the v1.0.1 tag.
