Serverless Api Manager

Optimized web framework for serverless environment

---

To prevent the cold-start of serverless functions from getting too long, a good alternative is not to use Express as it simulates the creation of an entire server and configures all routes and all middlewares of each of the routes, with only 1 being used.
