This merge request will fix #147 (closed). It is based on the existing implementation in the https://git.se.informatik.uni-kiel.de/stu128012/theodolite/-/tree/beam_current_theodolite fork but has to tackle the following requirements:

• Migrate the individual benchmarks with their new enumeration
  • Migrate UC1
  • Migrate UC2 (f.k.a. UC3)
  • Migrate UC3 (f.k.a. UC4)
  • Migrate UC4 (f.k.a. UC2)
• Migrate to Titan Control Center Commons 0.1.0 (Avro records and Schema Registry are already used)
• Fix code quality issues if any
• Support Docker builds (already available in the base branch)
• Build and push Docker images in CI pipeline
• Update Docker Compose files in docker-test
• Share code among Beam runners (either create subprojects or dedicated Gradle tasks or dedicated Dockerfiles or environment variables or ...)
• Clean up Gradle build files
• Provide corresponding Kubernetes benchmark definitions (might be tackled in a follow up ticket)
