Update existing objects with the latest version of the prototype.

prototype (str or dict): Either the `prototype_key` to use or the
prototype dict itself.
diff (dict, optional): This a diff structure that describes how to update the protototype.
If not given this will be constructed from the first object found.
objects (list, optional): List of objects to update. If not given, query for these

exact (bool, optional): By default (`False`), keys not explicitly in the prototype will
not be applied to the object, but will be retained as-is. This is usually what is
expected - for example, one usually do not want to remove the object's location even
if it's not set in the prototype. With `exact=True`, all un-specified properties of the
objects will be removed if they exist. This will lead to a more accurate 1:1 correlation
between the object and the prototype but is usually impractical.
