Delete pageviews in the same way as imported files

[ericholscher]

This is similar to #12386,
but trying to do a simpler version first.

Keep in mind that this will, whenever possible, be executed purely in SQL, and so the delete() methods of individual object instances will not necessarily be called during the process. If you’ve provided a custom delete() method on a model class and want to ensure that it is called, you will need to “manually” delete instances of that model (e.g., by iterating over a QuerySet and calling delete() on each object individually) rather than using the bulk delete() method of a QuerySet.

This is also called when a version is deactivated, do we want to remove pageviews in that case?

[ericholscher]

I'm not sure, tbh. I guess it's pretty aggressive, and might cause people to lose data?

You may want to call these on Project.delete and Version.delete only

This isn't necessary called when a project is deleted, it's also called from the admin. I'd put this under the delete method only (most of this data can be recovered, but pageview can't).
