Karyon2.0 (merge to master)

[karyon 2.0](https://github.com/Netflix/karyon/wiki/Karyon-2.0) release candidate changes.

Revamp of karyon to use [RxNetty](https://github.com/Netflix/RxNetty) as the transport and a better bootstrapping infrastructure as described in the wiki above.

Now, an application class can be written as follows:

```java

@ArchaiusBootstrap
@KaryonBootstrap(name = "hello-netflix-oss")
@Modules(include = {HelloWorldApp.KaryonJerseyModuleImpl.class, KaryonWebAdminModule.class, KaryonEurekaModule.class})
public final class HelloWorldApp {

    public static class KaryonJerseyModuleImpl extends KaryonJerseyModule {

        @Override
        protected void configure() {
            super.configure();
            bind(AuthenticationService.class).to(AuthenticationServiceImpl.class);
        }

        @Override
        public int serverPort() {
            return 8888;
        }

        @Override
        public int shutdownPort() {
            return 8899;
        }

        @Override
        public void configureInterceptors(GovernatorHttpInterceptorSupport<ByteBuf, ByteBuf> interceptorSupport) {
            interceptorSupport.forUri("/*").intercept(LoggingInterceptor.class);
            interceptorSupport.forUri("/hello").interceptIn(AuthInterceptor.class);
        }
    }
}
```

and then can be started running the main class `KaryonServer`  as

```
java com.netflix.karyon.KaryonServer com.netflix.hellonoss.server.HelloWorldApp
```

The example is provided in `karyon-examples/hello-netflix-oss` module.
