Summary: This is the first proposed approach to handle missing dependency in new_task.py by using a try block to import the functions defined in accelerator_lowering.py. This requires only changing a few lines of code in new_task.py where the functions lower_modules_to_accelerator and swap_modules_for_accelerator were called. Although swap_modules_for_accelerator doesn't require internal library, the accelerator decorator would be imported as a side effect. By wrapping it by the try block with lower_modules_to_accelerator during importing it would eliminate dependency of accelerator_lowering.py completely when not used.

Summary: Alternative approach to facebookresearch#1631. Handling ImportError of accelerator in accelerator_lowering.py instead of new_task.py. accelerator function is both used as a declarator on class AcceleratorTransformerLayers and called directly in lower_modules_to_accelerator. In addition to adding the try block for importing accelerator, accelerator_lowering_supported is used in lower_modules_to_accelerator to avoid ImportError.
