Prepare net release (#550)

* add public ServiceConfig::register constructor to support external configuration (#250)

* fix: doctest ServiceConfig::register() error (#250)

* add unit testing for ServiceConfig::register()

* replace pub(crate) to pub in ServiceConfig::new() (#250)

* replace pub to pub(crate) for ServiceConfig::new() and add pub for mod ntex::web::stack instead

* remove unsed DefaultError import in config.rs tests
