FEAT: Finalize Deployment, Update README.md
In this MR I have:
- Updated README.md to feature authors of this project and project deployment.
- Added caching and information about the test runner according to the CICD Seminar.
- Fix wrong env variables in users microservice.
- Finished Docker deployment
- Created initContainer for Postgres database, so the database does not contain hanging env variables.
- Delete version tag from docker compose, since it is deprecated.
- Various other changes.
