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

 ## Usage
 
 ntex supports multiple async runtimes, runtime must be selected as a feature. Available options are `compio`, `tokio`,
-`glommio` or `async-std`.
+`neon` or `neon-uring`.
 
 ```toml
 [dependencies]
-ntex = { version = "2", features = ["tokio"] }
+ntex = { version = "2", features = ["compio"] }
 ```
