Adjust docker compose setup to make local frontend tests work

Description

• follow up of tsm-orchestration#84 (closed)
• the possibility/functionality to run tests locally should stay in the tsm-frontend repository and not in the tsm-orchestration repository to avoid any problems with the deployment
• to run frontend tests, it should be possible to start the tsm-frontend repository without the tsm-orchestration
  • therefore some services must be mocked

Tasks

• find out which services must be mocked
• mock services in the docker compose setup
• make local testing possible
