Feature request: Add Event handler for Amazon VPC Lattice

[leandrodamascena]

Use case

With the general availability of Amazon VPC Lattice and considering that VPC Lattice supports Lambda as a target for VPC Target Group, then Powertools should add VPC Lattice as a new Event Handler to help customers easily manipulate routes, handle errors, custom response and so on.

This should have the same capabilities as other event handlers.

Solution/User Experience

import requests
from requests import Response

from aws_lambda_powertools.event_handler import VPCLatticeResolver
from aws_lambda_powertools.utilities.typing import LambdaContext

app = VPCLatticeResolver()

@app.get("/todo")
def get_todo():
    todos: Response = requests.get("https://jsonplaceholder.typicode.com/todos")
    todos.raise_for_status()

    # for brevity, we'll limit to the first 10 only
    return {"todos": todos.json()[:10]}

def lambda_handler(event: dict, context: LambdaContext) -> dict:
    return app.resolve(event, context)

Acknowledgment

• This feature request meets Powertools for AWS Lambda (Python) Tenets
• Should this be considered in other Powertools for AWS Lambda languages? i.e. Java, TypeScript, and .NET

Super interesting @leandrodamascena, this seems bigger than the event parser though. But let me know if you want to work on it :)
