Summary: In order to get rid of ClassyTrainer, we need to move num_dataloader_workers and dataloader_mp_context somewhere else. Move the context to the task and num_workers to ClassyDataset. This also changes the default multiprocessing context to spawn, for consistency. That required changing tests in fblearner to dev-nosan. This is a breaking change to the configs, and I'll announce it in the group before landing. Will also try to land other breaking changes at the same time to minimize disruption.
