Need a way to automatically update knowledge from the Neo4j DB to the Vector DB

**Is your feature request related to a problem? Please describe.**
We need an automated process to update the knowledge in the vector DB from the Graph KB.

**Describe the solution you'd like**
Whenever the knowledge is added to the AlzKB, we need to match this knowledge in the vector DB.
We may need to ADD, DELETE, UPDATE the knowledge.
This entails: Getting the updated relationships from AlzKB, translating into natural language, embedding and uploading the data.

**Describe alternatives you've considered**
We currently have the process in place to ADD data (without duplicates), but we need to design the proper way to handle DELETEs and UPDATEs

A few things we'll need:
- [ ] #67
- [ ] #68
- [ ] #70
- [x] Scripts to convert, parse, vectorize, tokenize and upload (these are ready and can be reused)
