The RabbitMQ 4.0 does not deal with client side `x-*` headers.
Therefore, an `x-death.count` is not incremented anymore when
message is re-published from client back to the broker.
* Spring AMQP 3.2 has introduced an `AmqpHeaders.RETRY_COUNT` custom header.
Use `messageProperties.incrementRetryCount()` in the `RabbitMessageChannelBinder`
when we re-published message back to the broker for server-side retries
* Fix docs respectively

This commit introduces new customization options for Kafka listener containers
in Spring Cloud Stream, along with comprehensive documentation:
- Add KafkaListenerContainerCustomizer interface for Kafka-specific customization
with access to extended consumer properties
- Extend ListenerContainerWithDlqAndRetryCustomizer to include access to
extended consumer properties
- Update KafkaMessageChannelBinder to support the new customizer interfaces
- Implement KafkaListenerContainerCustomizerTests for integration testing
- Add detailed AsciiDoc reference documentation explaining the purpose,
usage, and hierarchy of these customizer interfaces:
* ListenerContainerCustomizer (existing)
* KafkaListenerContainerCustomizer (new)
* ListenerContainerWithDlqAndRetryCustomizer (extended)
- Update navigation to include the new documentation
These changes enhance the flexibility and configurability of Kafka consumer
endpoints in Spring Cloud Stream applications, allowing users to fine-tune
their listener containers based on specific requirements and scenarios,
with improved access to Kafka-specific properties.
First, thanks for the excellent StreamBridge feature! I've found it very useful.
However, I occasionally encounter the following exception during race conditions.

BindingServiceProperties.bindings property should be thread-safe.
- Integrate KafkaConnectionDetails, a Spring Boot component, in binder
- Update KafkaBinderConfigurationProperties to use KafkaConnectionDetails
- Modify KafkaTopicProvisioner to leverage KafkaConnectionDetails
- Adjust Kafka binder configurations to pass KafkaConnectionDetails
- Update tests to accommodate KafkaConnectionDetails changes
- Add KafkaConnectionDetails to shared.beans for auto-configuration
This change improves flexibility in configuring Kafka connections,
allowing for better support of externalized configuration management
and aligning with Spring Boot's connection abstraction model.
The getBinder method in DefaultBinderFactory was made thread-safe using ReentrantLock. This commit ensures that the method is friendly for virtual threads to avoid blocking and pinning. The lock is acquired at the beginning of the method and released in a finally block to ensure it is always released, even if an exception occurs. Fixes gh-3004

* Enable native observability support for output binding in the reactive Kafka binder
* Adding test to verify this support with downstream consumers
* Adding ref docs
* Addressing PR review
Spring for Apache Pulsar introduced support for default tenant and namespace
for Pulsar topics in 6d23378fbb.
This ensures that all topic names are fully-qualified (using the default
tenant and namespace when not fully-qualified).
