Description

Refactorization of Dockerfiles / docker-compose

docker-compose: Introduced preparation as new dummy service which will not run. -- preperation downloads all maven dependencies required for the common and the service package. -- preperation generates the .jars for the other services.
Dockerfiles: All regular services no longer download maven dependencies or perform compilations. Instead, they use the .jars provided by the preperation service.

Due to these changes, maven dependencies are only downloaded once and the code is only compiled once. This leads a sizeable speedup for $ docker-compose build.
