Design and implement generic way to set parameters for applications/adapters

[avavilau]

MVP cases:

Usecase	Deployment	User	Comments
Model selection	DIAL RAG	UI Users / Derived applications which uses RAG API
Error reporting type	DIAL RAG	Web RAG Programmatically
Dataset selection	danswer app	UI User
Dataset list	danswer app	UI User
Retry count	SUB-PROJECT-1	UI User, potentially API user
Get data	StatGPT	IMF UI User	Option is only available when all query parameters are filled
Select API Search indices or copilot	MSFT RAG demo	Sales person

Seems like we have at least two simple cases:

1. Application Settings
2. Contextual commands
