Injecting parameters into OAuth services

[oniric85]

Hi,
I'm trying to inject some parameters through setters into the OAuth services. The base library you are using has some services which have setter methods to configure specific options. For example:

https://github.com/Lusitanian/PHPoAuthLib/blob/29bda6e176df6c292a9b1c43ae8a44d56a87c30b/src/OAuth/OAuth2/Service/Strava.php#L131

I've built a custom OAuth service and now I would like to do a similar thing using silex-oauth but I can't access services directly because they are stored in the ServiceRegistry and if I try to get a service from there with a getService call I get an exception:

RouteNotFoundException in UrlGenerator.php line 134: Unable to generate a URL for the named route "_auth_service_callback" as such route does not exist.

I guess that's because the route is created when the OAuthAuthenticationListener is created too while I'm trying to access the OAuth Service from another ServiceProvider I'm writing.

Is there a way provided by the library to achieve what I'm trying?
