Subject: [PATCH] Handle AttributeError in etcd.py (#1801)

When the__del__() method is executed the python interpreter already unloaded some of the modules that are still used down the http.clear() method.
The only we could do in this case - silence some exceptions like ReferenceError, TypeError, AttributeError.
