Async factories

[schiller-manuel]

Did you consider adding support for async factories?

This is how an async factory might be used:

class Server {
    public async init() {
    }
}

async function serverFactory() {
    const server = new Server();
    await server.init();
    return server;
}

class App {
    public static inject = ['server'];
    constructor(private server: Server) {
        // server is already initialized
   }
}

const injector = createInjector().provideFactory('server', serverFactory);
const app = await injector.injectClass(App);

Yeah, this would be a great addition. Have thought about it, sure can be added, just haven't got around to it yet.

I find your solution elegant. I was thinking about adding provideAsyncFactory, but if we could add it with the existing provideFactory that would be better.
