This adds real support to Vapor to make it easy to integrate different services that can be tested.

For example, if you have a service defined as:

protocol MyService {
    func `for`(_ request: Request) -> MyService
    func doSomething() -> String
}

You may then have a real implementation:

import Vapor

struct MyRealService: MyService {
    let logger: Logger
    let eventLoop: EventLoop
    
    func `for`(_ request: Vapor.Request) -> MyService {
        return MyRealService(logger: request.logger, eventLoop: request.eventLoop)
    }
    
    func doSomething() -> String {
        return "Tada"
    }
    
}

This is a very contrived example, but shows a service that needs a Logger and EventLoop - things that are normally tied to specific requests. Doing this in a safe and testable way involves a lot of boilerplate. This moves the boilerplate into Vapor to make it easier to do.

extension Application.Services {
    var myService: Application.Service<MyService> {
        .init(app…
