fix(apache#1980): Implement data type support in KameletBinding

- Support data type reference in KameletBinding that automatically adds data type action Kamelet to the resulting integration template flow
- Allow the user to specify the data types for output/input on Kamelet references in a binding
- Camel K automatically adds respective steps (using the data-type-action Kamelet) in order to apply the data type conversion logic
