      Currently, the public methods take in a DocumentSource pointer and give information about that inputs of that stage. vesko.karaganev@mongodb.com pointed out that it'd be nicer if callers could explicitly request either behavior, e.g. something like:

      canPathBeArray(LookupScope::inputs(stage), path)  
canPathBeArray(LookupScope::outputs(stage), path)
