Allow sending an intent to a specific capability

Is your feature request related to a problem? Please describe.

When modeling UI components via Intention API, the integrator typically issues an intent when the user interacts with that component. However, if there are other capabilities that match the qualifier of the capability, the intent is transported to them as well, leading to unexpected behavior.

Describe the solution you'd like

This intent should be transported exclusively to the provider of the capability, even if there are other capabilities that match the qualifier.

In this particular use case, I could imagine passing the capability identifier to the IntentClient instead of the type and qualifier.
