20768	Create a reference of public Manager methods	Ramiro Morales	Clifford Gama	"In the ""Natural keys"" documentation, an example of a custom manager's `get_by_natural_key()` method calls `self.get()` (https://docs.djangoproject.com/en/dev/topics/serialization/#deserialization-of-natural-keys) but we don't document which the available methods are.

We should expand the reference-type documentation of manager, even if only to note some of them simply proxy to the respective !QuerySet methods:
