wip: added --no-schema option scaffolding, needs tests

[morganhein]

This adds the --no-schema option, which allows for overriding the default option in the driver.

This flag only allows forcefully ignoring the schema, setting --no-schema=false does not force usage of the schema.

This code works, but I'd like some feedback on what else needs to be updated to make this land.

I don't feel confident deciding which tests to update for this, nor if you'd like README stuffs to be updated.

Any guidance is welcome, and i'll do what I can.

Thanks!
