[Feature Request]: Caching the snowflake connection

### What would you like to happen?

I would like to request the new feature for caching the snowflake connection once logged in successfully. Currently the connection is discarded after query execution this could cause issues when too many requests via externalbrowser authentication take place.

### Issue Priority

Priority: 3

### Issue Component

Component: API

The issue names the API component, Snowflake connections, query execution, and externalbrowser authentication, but no files or tests. Start by locating the API entry point that creates and discards the connection after a query. Done means a successfully authenticated connection can be reused for later requests without repeated externalbrowser authentication.
