[IMPORTANT] Create kubernetes deployment setup

Since the new AIoD platform is eventually supposed to be deployed on Kubernetes cluster, we should make it Kubernetes ready by testing it locally and preparing deployment config files

BLOCKER:
- [ ] We need to split the application into parts that are stateless and that are not
- API handling can be easily replicated together with query processing (Each replica would have its own embedding model)
- The recurring sync up with AIoD platform cannot be duplicated to each replica...
- The same goes for database -> For now only one DB instance should suffice (applies for both Milvus and TinyDB)
