Type of Change

Added pinecone support for the ChatQnA application

Description

I updated the server.py class in the qna-app/app directory to initialize the vector store according to the vectordb argument. Additionally, I made corresponding changes in the utils.py helper class to handle this functionalit,y

I included the "pinecone" folder containing the "ingest.py" and rag_pinecone folder with "chain.py" files and more.

How has this PR been tested?

This pull request has been tested, following the same procedure as the existing RAG flow. The main difference is that the vectordb parameter was set to "pinecone", and a few additional environment variables were configured in the docker-compose-pinecone.yaml file to use the pinecone vectordb. Did the regression testing for redis-db as well.
