Here's a good function header given the following:
I wrote the below code

    orig_add_image = glanceclient.v1.images.ImageManager.create
    def fake_create(context, metadata, data=None):
        sent_to_glance['metadata'] = metadata
        sent_to_glance['data'] = data
        return orig_add_image(metadata, data)
    stubs.Set(glanceclient.v1.images.ImageManager, 'create', fake_create)

What's a good function header?
