[api/compiler] @Factory annotation parameters

[Gmugra]

Idea is to extend @Factory annotation with optional parameters which works like methods from ConfigFactoryBuilder:

@Factory(
    sources = { "classpath:my.properties", "system.properties" }, 
    loadStrategy = LoadStrategy.FIRST,
    autoReload = true,
    globalPrefix= "gp"
)
public interface MyFactory {
    MyConfig createMyConfig();
}
