User Interface to manage additionalProperties

[Delawen]

Please describe the feature that you want to propose

Some of the DSLs we support (Integration, Kamelet and Kamelet Binding) are Kubernetes Resources that have additionalProperties. We would need a generic extension UI that can list the additionalProperties and edit them.

The annotations are stored on the metadata/additionalProperties of the flow object returned by the backend.

The backend needs to add a boolean in the dsl capabilities endpoint explaining if this UI is shown or not by DSL.

What type of object is additionalProperties, a dictionary? What values can be stored in here? Maybe this could re-use the same component as #2160 unless maybe if the values need to be typed properly.
