**Description**
This PR adds API handling capabilities to the Synapse Go implementation,
including a flexible HTTP router with versioning support, robust validation,
and graceful shutdown handling.
**Features**
* Dynamic HTTP routing based on API definitions
* Support for multiple versioning strategies (Context version strategy and
URL version strategy )
* Comprehensive API validation for context and version configuration
* Automatic server lifecycle management with graceful shutdown
* Proper error handling throughout the request/response pipeline
* Thorough unit tests for all new functionality
**Implementation Details**
**API Routing**
* Added a new `RouterService` in the `internal/pkg/core/router` package.
* Implemented dynamic route registration based on API resources.
* Added support for HTTP method filtering in route handlers.
* Integrated API context and versioning in the URL path construction.
**API Validation**
* Enhanced API unmarshaling to validate mandatory fields (context, name).
* Added validation for context format (must start with '/').
* Implemented version and versionType consistency validation.
* Added proper versioning type validation ("url" or "context").
**Server Lifecycle**
* Implemented automatic HTTP server startup when APIs are registered.
* Added context-based graceful shutdown mechanism.
* Proper cleanup of resources during shutdown.
**Additional Changes**
* Updated deployment process to register APIs with the router.
* Enhanced message context with request handling capabilities.
* Added documentation in the README.
**Testing**
The implementation includes comprehensive tests for:
* API routing and request handling
* Versioning strategies (URL and context-based)
* API validation for different scenarios
* Edge cases like placeholder handling, trailing slashes
This feature allows Synapse Go to handle API definitions in a way that's
consistent with the original Apache Synapse, providing a solid foundation for
RESTful API management.
