While hardcoding primary key values in the Django test suite is avoided as
much as possible, sometimes there are legitimate uses. The existing
hardcoded integer values, however, don't work on databases that don't use
integer primary key values. For example, MongoDB uses `DEFAULT_AUTO_FIELD
= "django_mongodb_backend.fields.ObjectIdAutoField"`.
I propose adding new methods `DatabaseOperations.get_hardcoded_pk()` and
`get_nonexistentd_pk()` to allow a database backend to provide suitable
values, minimizing the size of the Django fork needed for running the test
suite on such databases.
