Show an example on how to use APP_INITIALIZER to set AuthConfig

[guidoffm]

At the moment all examples use configuration in code.

If you want to package your app and want to deploy it to different environments this is not optimal.
It would be better to load the configuration at runtime.

I will offer an example by myself soon.

Examples are always welcome I think!

Curious to hear also what the practical use case would be to do it in the initializer? I find that to use Angular's environment I can just use this setup:

{ provide: AuthConfig, useValue: myConfigUsingEnvironment }

or alternatively with useFactory instead.

We actually use a factory in one of my applications, that contains some logic to look at window.location.hostname to tweak some things in the config.

Either way, would be nice to see an APP_INITIALIZER example too!
