CloudEA Integration (QM, Rules, Actuator) (#22)

* Add Class to Calculate Score of CloudEA Quality Model
* SecurityScore implemented
* Adjustment according to the Score interface.
* Changes in SecurityScore
* Added the Scores (SecurityScore and PrivacyScore) to TrustworthinessScore
* Adjusted the tmalibrary (actuator) to work properly with Python3
* Python Actuator Library Fix
* Updated submodules.
