31007	Make it possible to change the default AutoField to BigAutoField.	Caio Ariede	Tom Forbes	"This was initially proposed in this comment/PR: https://github.com/django/django/pull/8924#issuecomment-516792989

1. I really like the proposed approach of having a `DEFAULT_AUTOFIELD` setting.
2. For backwards compatibility, when `DEFAULT_AUTOFIELD` is not set, we should keep the default behavior: `django.db.models.AutoField`
3. Whenever this setting is changed, it would affect all existing AND new fields (pk and fk)"	New feature	closed	Database layer (models, ORM)	dev	Normal	fixed		Tom Forbes	Ready for checkin	1	0	0	0	0	0
