Increase Context for Grounding in RAG

[nicoloesch]

Motivation

Currently, the RAG-based grounding just receives the label and the embedding for it.
Provide the option for auxiliary context in the retrieval, e.g.:

• Surrounding text that could clarify the acronym used (EGFR: genomic mutation, or glomerolous filtration rate?)
• Domain given the context
• Question/Answer context

Pitch

Provide an interface for the embedding-based resolving that allows to ingest additional context that could provide better grounding
