AWS SAM expects an integer status code

[mathom]

The current response returns a stringified statusCode. This jams up AWS SAM when it's ran locally:

2019-02-12 11:04:31 statusCode must be a positive int

Here's the SAM setup to reproduce this:

requirements.txt:

aws-wsgi==0.0.8
Flask==1.0.2

api.py:

import awsgi
from flask import jsonify, Flask

app = Flask(__name__)

@app.route('/')
def index():
    return jsonify(message='OK')

def lambda_handler(event, context):
    return awsgi.response(app, event, context)

template.yaml:

AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::Serverless-2016-10-31'
Resources:
  AppExample:
    Type: 'AWS::Serverless::Function'
    Properties:
      Handler: api.lambda_handler
      Runtime: python3.6
      CodeUri: .
      Events:
        HTTPRoot:
          Type: Api
          Properties:
            Path: /
            Method: any

Test locally:

sam build && sam local start-api --template .aws-sam/template.yaml

@mathom Thanks for this very well-written PR! Merging this would break backward compatibility, and after a little digging I think the solution would be to fix SAM CLI to handle a string statusCode.

I'm working on that PR now and once it's released I'll decline this one. Be back in a bit with a link to that.
