Added support for MongoDB Export of results for Instruction/Prompt Template

[pramitbhatia25]

Summary of changes: Added export to_mongo_db option after generating results. Added error handling in experiment.py to_mongo_db function. Modified open_ai_chat_completion and open_ai_chat experiments, made them set completion functions only if DEBUG key doesn't exist. Modified load_data function in data_loader.py to return a dict. If there's any error, it is displayed on the UI instead of the app crashing. Added Anthropic / Google PALM / LlamaCpp Completion models in data loader so they don't error out when called. (Support for these still needs work)

Important: Since I've modified data_loader.py / experiment.py, and the playground imports these from the prompttools package, we'll need to release a new version and update it. (I've tested the functions by using them directly in playground.py, they were working fine..)

Hey guys. let me know if I should make any more modifications. I'm working on the to_mongo_db connection for Model Comparison, will need to modify the run_multiple function in data_loader.py file to get it working.

This is a great start!

• You'll need to rebase on the latest changes from today, we're updating the UI a bit
• Could you attach a few screenshots to show how the UI will look with these changes?

One more idea here: can we use streamlit's connectors for mongodb?
