Add temporary functiontal tests, that must be removed soon.

Refactor tests: Remove outdated resource manager tests and add functional tests with Docker and Kafka integration

- Deleted existing unit tests for ResourceManager.
- Introduced new functional tests for single node operations with Redis and Kafka.
- Added Docker Compose setup for test environment.
- Implemented fixtures for Redis and Kafka consumers.
- Created comprehensive tests for data publishing and slot management.
- Added unit tests for DataManager and IngestorManager with mocked dependencies.
- Included tests for OpcManager covering connection, subscription, and data change notifications.
