Store the alias used to fetch a cache backend instance on the instance
itself. The Django Debug Toolbar is having to do some extra patching
(django-commons/django-debug-toolbar#2219) to retain what alias is being
used for which cache. While tolerable, it means the toolbar is having to
reimplement more parts of Django, making it more brittle for future
versions.

Ideal code:
{{{
from django.core.cache import cache
print(cache.alias)
# "default"
}}}
I believe we need to make the following changes:
- Update CacheHandler.create_connection to pass alias as
backend_cls(location, params, alias=alias)
- Update django.core.cache.backends.base.BaseCache.__init__ to accept and
store alias
