  - Fix sub-attribute parsing for accessing resolved values

    Added assignment-map attribute to ResourceResolutionComponent.
    This attribute will hold a json object with the resolved values
    for each artifact-prefix. It will enable accessing any resolved
    value, using get_attribute with JsonPath.
