      Since PYTHON-1101 made the default write concern (WriteConcern()) evaluate to False it is not possible to override a write concern with the default.

      >>> client = MongoClient(w="majority")
>>> client.write_concern
WriteConcern(w=majority)
>>> client.get_database("test", write_concern=WriteConcern()).write_concern
WriteConcern(w=majority)
>>> WriteConcern() or WriteConcern(w='majority')
WriteConcern(w=majority)

      I propose we just remove the __bool__ and __nonzero__ methods as the behavior it causes is not intuitive. This would be a minor change in behavior that I bet no one externally relies on.
