Server generalization

This is a generalization of things I often do with express servers.

Because I ended up repeating code by copy pasting, I've done this project to generalize these aspects:
- Dynamic server configuration

If anther server's ip / port changes this one has a route to discover it.
That which other servers will send a request to.

Your app will not be able to use '/srv' because it's reserved for server configuration, like discovery.

- Server creation
- Middleware usage
- Users folder
- Protection
- Server clustering
