[Host.RabbitMq] Add RabbitMQ Publisher Confirms (Opt-In)

[zarusz]

Feature Request: Add RabbitMQ Publisher Confirms to SlimMessageBus (Opt-In)

Description:

Introduce support for RabbitMQ Publisher Confirms in the SlimMessageBus library as an optional feature. Publisher Confirms provide a reliable mechanism for ensuring that messages published to RabbitMQ are successfully received by the broker. This feature is critical for scenarios where guaranteed message delivery is a priority.

Background:

RabbitMQ Publisher Confirms offer a robust way to handle acknowledgment of published messages, ensuring they are properly queued. This mechanism is well-documented and widely adopted in systems requiring high reliability. Adding support for this feature would enhance the library's reliability and extend its utility in more demanding production environments.

• RabbitMQ Documentation on Confirms: [Publisher Confirms](https://www.rabbitmq.com/docs/confirms#publisher-confirms)
• Example Implementation in C#: [Publisher Confirms in RabbitMQ](https://rianjs.net/2013/12/publisher-confirms-with-rabbitmq-and-c-sharp)

Suggested Implementation:

• Add an optional configuration in SlimMessageBus for enabling Publisher Confirms.
• Provide a clear API or settings to enable this feature at the bus or message producer level.
• Implement appropriate acknowledgment handling logic, allowing applications to act on success or failure of message publication.
• Include documentation and examples to demonstrate how to use this feature.

Related Discussions:

• Refer to this [comment]([Host.RabbitMQ] Add ability to configure connection retry attempts and delay #310 (comment)) in GitHub Issue [Host.RabbitMQ] Add ability to configure connection retry attempts and delay #310 for further insights on potential implementation and community interest.

Benefits:

• Improves reliability for message delivery in RabbitMQ.
• Enhances SlimMessageBus's appeal to developers seeking robust message handling.
• Provides an opt-in mechanism, ensuring no breaking changes for existing users.

Thank you for considering this enhancement!
