Register a backward hook common to all the modules.

This function is deprecated in favor of
[tensorplay.nn.modules.module.register_module_full_backward_hook()](tensorplay.nn.modules.module.register_module_full_backward_hook.html#tensorplay.nn.modules.module.register_module_full_backward_hook)
and the behavior of this function will change in future versions.

Returns:

a handle that can be used to remove the added hook by calling
handle.remove()

Return type:

tensorplay.utils.hooks.RemovableHandle
