Create new example for an echo-bot using AWS Lambda Functions, `linebot.v3`

Problem

Recently, while developing a Line Bot and working with AWS services, I noticed a lack of examples using linebot.v3 with AWS Lambda Functions. Therefore, I've created a Line Bot architecture using AWS Lambda Functions in a serverless setup. Below is the architecture diagram.

Source Code

import json
import os

from linebot.v3 import WebhookHandler
from linebot.v3.messaging import (ApiClient, Configuration, MessagingApi,
                                  ReplyMessageRequest, TextMessage)
from linebot.v3.webhooks import MessageEvent, TextMessageContent

configuration = Configuration(access_token=os.getenv('CHANNEL_ACCESS_TOKEN'))
handler = WebhookHandler(os.getenv('CHANNEL_SECRET'))

@handler.add(MessageEvent, message=TextMessageContent)
def handle_message(event):
    with ApiClient(configuration) as api_client:
        line_bot_api = MessagingApi(api_client)

        line_bot_api.reply_message_with_http_info(
            ReplyMessageRequest(
                reply_token=event.reply_token,
                messages=[TextMessage(text=event.message.text)]
            )
        )

def lambda_handler(event, context):
    try: 
        body = event['body']
        signature = event['headers']['x-line-signature']
        handler.handle(body, signature)
        return {
            'statusCode': 200,
            'body': json.dumps('Hello from Lambda!')
        }
    except Exception as e:
        return {
            'statusCode': 500,
            'body': json.dumps(str(e))
        }

Solution

I will submit pull requests to create the new example -- aws-lambda-echo/ along with the necessary documentation. Additionally, I will include the requirements.txt file and a comprehensive README.md.

If it's convenient, you can also assign this feature to me so that I can contribute to the line-bot-sdk-python development.
