Expand CI/CD to test each docker-compose service

This is a list of integration tests that could be executed, seperated into groups which represent a creation of something and the following actions that correspond to it:

---

• check if all services are running and healthy trough docker ps

---

• create an mqtt-user and check if he gets created successfully
• check if the user can send data to his topic-namespace

---

• create a thing and send it to the broker
• check if the thing goes trough the dispatcher
• check if a minio user/bucket gets created
• check if the postgres database role and schema get created
• check if the thing entity gets created inside the thing table

---

• upload mocked csv data to minio
• check if run-process-new-file-service gets notified by mqtt
• check if the data can be found on minio (with the correct tags?)

---

• check if parsing is working correctly
• (check if visualization is working correctly (url reachable?))
