Feature request: Add Event handler for AWS Lambda Function URLs

Use case

With the general availability of AWS Lambda Function URLs to implement microservices AWS Lambda Powertools for Python should support handling this event type.

This should support the routes being specified in a separate file just like for other event handlers.

Solution/User Experience

from aws_lambda_powertools import Logger, Tracer
from aws_lambda_powertools.logging import correlation_paths
from aws_lambda_powertools.event_handler import FunctionUrl

tracer = Tracer()
logger = Logger()
app = FunctionUrl()

@app.get("/hello")
@tracer.capture_method
def get_hello_universe():
    return {"message": "hello universe"}

# You can continue to use other utilities just as before
@logger.inject_lambda_context(correlation_id_path=correlation_paths.FUNCTION_URL)
@tracer.capture_lambda_handler
def lambda_handler(event, context):
    return app.resolve(event, context)

• This feature request meets Lambda Powertools Tenets
• Should this be considered in other Lambda Powertools languages? i.e. Java, TypeScript

Ok, I will just wait for a status change on this or to hear back from ya’ll.

@michaelbrewer – after looking at the code last night it looked like it would “just work”. It would still be nice to have an explicit class for it.

I know ya’ll did some work on this already – would you mind/like if I took a crack and submitted a Pull Request with it (assuming that I have time before August)?
