django.db.migrations.swappable_dependency not documented

[Shai Berger]

As far as I could see, django.db.migrations.swappable_dependency (which is used in migrations whenever the operations need to create a FK to a swappable model) is not documented at all. It needs to be documented because, although it usually shows up in generated code, that code is considered as user-code and should be possible to write by hand as well.
