Introduce AsyncAPI for messaging modules

[pierissimo]

Background

Describing the Event-driven architectures can be challenging, as the OpenAPI specification is primarily focused on describing RESTful APIs.
AsyncAPI is an open-source initiative that aims to provide a way to describe event-driven architectures using the OpenAPI-like specification.

Proposed Solution

To address this issue, it is proposed that the DaVinci framework include an AsyncAPI module. This module would provide developers with a way to describe event-driven architectures. Additionally, it would provide a set of tools and functions that developers can use to generate code and documentation from the AsyncAPI specification.

The proposed solution would involve the following steps:

• Create a new module within the framework that is responsible for providing AsyncAPI functionality.
• Provide a set of decorators and tools that developers can use to describe event-driven architectures using the AsyncAPI specification.
• Provide a way for developers to generate code and documentation from the AsyncAPI specification.
• Provide documentation and examples that show developers how to use the AsyncAPI module.
