Great initiative! Left some comments - especially the OpenAPI schemas are needed. Also, we should replace the old integration tests with new ones that cover the main use cases.

As SQLLAB_BACKEND_PERSISTENCE has been enabled for quite some time by default, I wonder if we should just remove the FF and clean up these conditionalities. Thoughts @dpgaspar @betodealmeida ?

We need to add the schema spec here, otherwise we won't get an API spec:

I'm trying to use the SqlLab API that has recently been migrated to api/v1/sqllab and am having some difficulties. I can get the api/v1/sqllab/execute endpoint to work fine but don't seem to be able to successfully do an async execute followed by a api/v1/sqllab/results call to get the resulting data rows of the execute. Also I'd like to get the rows in chunks instead of all at once but am unsure if this is supported. Example Python code of an async execute followed by one or more results calls would be very helpful.
