Integrate swift-configuration

[adam-fowler]

An initial attempt at integrating swift-configuration

let router = Router()
    .get("hello") { request, _ -> String in
        return "Hello"
    }
let httpConfig = configReader.scoped(to: "http")
let app = Application(
    router: router,
    server: .http1(configuration: .init(reader: httpConfig))
    configuration: .init(reader: httpConfig)
)
// run hummingbird application
try await app.runService()

That was quick, @adam-fowler. Looks good to me. Also a great example of how to integrate Swift Configuration using Traits, including Swift version support. 👍
