Wrapper to make functions for simple HTTP request/response functions cloud-agnostic.

Currently supports:

• AWS Lambda
• Azure Functions (v2)
• Google Cloud Functions
• OpenWhisk (used by IBM cloud functions)

For uniformity, this also implements its own HttpRequest and HttpResponse objects.

The function that is wrapped takes a single argument (of type HttpRequest) and should return a single HttpResponse.

from proxy import proxy

def func(req):
    ...

main = proxy(func)
