Adaptation of Kieker to the JPMS

[Marcel-Ha]

Pull Request

Contribution

This pull request provides the following contribution to Kieker

• Adds module-info files to all Gradle subprojects, effectively turning the subprojects into JPMS modules.
• Adapt the build.gradle files:
  • to handle dependencies for the module path (Kieker uses a lot of non-JPMS libraries and therefore needs to read the unnamed module) and some fixes
  • to make trace analysis use the module path and run as a module. (Only trace-analysis for now, as the other tools have not been tested yet)

Open TODOs

• Update names of modules.
