For the current implementation of muxing we only need to match a single Persona at a time. For example:

1. mux1 -> persona Architect -> openai o1
2. mux2 -> catch all -> openai gpt4o

In the above case we would only need to know if the request matches the persona Architect. It's not needed to match any extra personas even if they exist in DB.

This PR introduces what's necessary to do the above without actually wiring in muxing rules. The PR:

• Creates the persona table in DB
• Adds methods to write and read to the new persona table
• Implements a function to check if a query matches to the specified persona

To check more about the personas and the queries please check the unit tests
