Enhancement: allow async exception handlers

[audiovention]

Summary

I want to log my exceptions, but also log the request headers and body when an exception occurs. Basically what LoggingMiddlewareConfig does, but only when an exception occurs.

Basic Example

I tried to go the route of the example here - https://github.com/litestar-org/litestar-pg-redis-docker/blob/78094bc4ea82839ba8703a41381da1e60f0b1d4d/app/core/exceptions.py Here's my code

async def logging_exception_handler(request: Request, exc: Exception) -> Response[Any]:
    logging_middleware_config = LoggingMiddlewareConfig()
    extracted_data = await logging_middleware_config.middleware_class.extract_request_data(request)
    logging_middleware_config.middleware_class.log_message(values=extracted_data)
    logger.error("Application Exception", exc_info=exc)
    return ExceptionHandlerMiddleware(
        app=request.app, debug=request.app.debug, exception_handlers={}
    ).default_http_exception_handler(request, exc)

However, the problem is that the exception handler cannot be async. At the same time it seems that I need to await the request body in this handler, so I'm kinda stuck in a pickle.
