Serve http events with webpack-dev-server

[thenikso]

Inspired by elastic-coders/serverless-runtime-webpack#8 it could be useful to have a command to run a local server simulating the API Gateway. It could be something like:

$ serverless webpack serve --port 8000
Serving endpoints: 
GET - http://localhost:8000/dev/hello
POST - http://localhost:8000/dev/user/{userId}

What do you think? how would you go in implementing this?
