return statusCode ignored, move statusCode to body?

My actions before raising this issue

[x] Followed the troubleshooting guide
[x] Read/searched the docs
[x] Searched past issues

Expected Behaviour

The return status code should be returned along with the body message.

Current Behaviour

The return 'statusCode' is currently seems to be completely ignored when using curl on an OpenFaas function endpoint. There doesn't seem to be a mechanism to retrieve the statusCode (maybe I'm missing something in the documentation).

Possible Solution

Include the status code in the return body so it can be parsed by end users. As suggested here, https://github.com/openfaas/faas-netes/issues/147#issuecomment-367953472

i.e. in handler.py

def handle(event, context):
    return {
        "body": {
            "statusCode": 200,
            "message": "Hello from OpenFaaS!"
        }
    }

Steps to Reproduce (for bugs)

Modify one of the template handler.py return status codes to be something other than 200 (e.g. 500)
build, push, deploy a container using the template modified
execute the function and check the return status

Context

I'm a graduate student working on a masters capstone comparing performance and cost of cloud native applications running with open sourced software to proprietary solutions from cloud vendors.
