There's a bunch of logic in
django/db/__init__.py that loads the appropriate backend from
django.db.backends based on the
DATABASE_ENGINE setting. We should put this logic into a function so it can be used by other code.
The specific use-case is multiple-database code that needs to load a separate backend for each database connection.
See discussion in this django-developers thread, starting with Yuri Baburov's comment.
