[crag] Ignore executor config when using execute_in_process
Summary: Currently, we foist the original config from the job into execute_in_process. This means that we might end up with executor config that doesn't make any sense. This diff makes execute_in_process ignore that extra config.
Test Plan: Added test to ensure executor config is ingored
