PlantUML generator: fix label for Conformist pattern

[stefan-ka]

This issue concerns the PlantUML component diagram generator. At the interface usage there is a label which states the used aggregates and the downstream DDD pattern. The following two cases are possible right now:

• use aggregates [aggregates] via ANTICORRUPTION_LAYER
• use aggregates [aggregates] via CONFORMIST

However, the word "via" does not make sense in the Conformist case. The generator shall be changed so that the two cases are generated as follows:

• use aggregates [aggregates] via ANTICORRUPTION_LAYER
• use aggregates [aggregates] as CONFORMIST

Solved. The label distinguishes how between ACL and CF:
