feat: support for declarative management of dependent resources

- Kubernetes-native resources are automatically handled without users
  having to deal with explicit event sources
- Reconcilers and event sources can exchange information via the
  `EventSourceContext`
- Declarative management is completely opt-in and can cohabit with
  "traditional" handling i.e. it's possible to have only part of the
  dependents being declared via annotations and others explicitly
  handled (though from a maintenance perspective it's better to stick
  to one approach or the other)
