[question] pre-configure route builders at build time

As today we do not perform so may optimizations and introspection to the routes so we may introduce a new annotation to give some hints to the build processor about in which phase a route is expected to be configured and some additional meat-data like classes that need to be registered for reflection, like:

```java
import org.apache.camel.quarkus.annotations.Configure;
import io.quarkus.deployment.annotations.ExecutionTime;

@Configure(ExecutionTime.STATIC_INIT, reflectiveClasses = { "com.acme.MyBean" })
public class MyRouteBuilder extends RouteBuilder {
@Override
public void configure() {
from("somewhere")
.bean("com.acme.MyBean", "doSomething");
}
}
```

toughs ?

The issue names no repository files or tests. Start by reviewing the proposed @Configure annotation, Quarkus ExecutionTime, and the build-processor approach described in the example. Done would mean an agreed design for build-time route configuration and reflective-class registration.
