LinkRestAdapter - a generic LR extension mechanism

[andrus]

Define LinkRestAdapter interface - a generic LR extension mechanism that would allow to customize a bunch of services at once. This would allow Sencha specific extensions, but also pretty much any kind of customization that LR DI allows. Here is a proposed API, allowing to contribute to both internal Injector and JAX RS Feature:

public interface LinkRestAdapter {
    void contributeToRuntime(Binder binder);
    void contributeToJaxRs(Collection<Feature> features);
}
