AWS Lambda Adapter: Expose aws_request_id and log_stream_name in SlackRequestHandler context

I would like to add two parameters from the AWS Lambda context into the BoltRequest context in AWS :

• aws_request_id
• log_stream_name

These parameters are useful for manual logging and are accessible directly from the context variable within lambda_handler(event, context) function when not in Bolt framework. I would like to also make them available in Bolt framework. Proposed code mirrors how bolt_req.context is currently populated in AWS Lambda adapter handler:

             bolt_req.context["lambda_request"] = event
             bolt_resp = self.app.dispatch(bolt_req)

I am open to implementing this feature myself if there is desire to add it to bolt-python.

slack_bolt/adapter/aws_lambda/handler.py から始めます。ここで SlackRequestHandler は AWS Lambda のコンテキストを bolt_req.context にマッピングします。既存のコンテキストの設定を確認し、他の Lambda 値とともに aws_request_id と log_stream_name を公開します。Bolt リクエストの処理中に両方のキーが利用可能になれば完了です。
