Move the events admin views to the admin model
One-sentence description
Move the events admin views to the admin model
Why?
It improves our codebase
Current implementation
We have a admin_views.py and admin.py. The admin views are routed through urls.py, not the admin.
Suggested implementation
Override the url config of the model admin used for events to add our custom views. Just like here: https://docs.djangoproject.com/en/2.1/ref/contrib/admin/#django.contrib.admin.ModelAdmin.get_urls
