> Assert if code tries to access SQLConf.get on executor.
> This can lead to hard to detect bugs, where the executor will read fallbackConf, falling back to default config values, ignoring potentially changed non-default configs.
> If a config is to be passed to executor code, it needs to be read on the driver, and passed explicitly.
