Support for preconditions for constraints and concept

[obfischer]

I am working on a self-contained system with some internally used libraries and some micro services.

Writing and organising constraints and concepts for such a project becomes difficult if some constraints/concepts should be applied only to libraries, some only to service and other to both.

Of course this problem is solvable by splitting concepts/constraints into multiple plugins and an appropriate Maven setup. On the other side this adds to and spreads complexity over the hole project setup.

Therefore I would like to see jQAssistant supporting Cypher based preconditions. Only concepts/constraints with fulfilled preconditions should be executed.
