* Disable changing special exam type after release date

Do some client-side validation to make sure that exams
that *are* or *ever were* special may not be changed
to a special exam type (other than the current one)
after release date.

Allow reset for visible missed dates

Fixing RemovedInDjango30Warnings

**Background:** The `django.shortcuts` method `render_to_response` became deprecated in [Django 1.3](https://docs.djangoproject.com/en/3.0/releases/1.3/), when  `render` was introduced.

Per the documentation:

> render() is the same as a call to render_to_response() with a context_instance argument that forces the use of a RequestContext.

Both return an `HttpResponse` object.

**Context:** We changed two statements: An import line and the call to the method, adding explicit parameter names to improve readability.

**Before:**
```
from django.shortcuts import get_object_or_404, render_to_response
...
return render_to_response("teams/teams.html", context)


```

**After**
```
from django.shortcuts import get_object_or_404, render
...
return render(
            request=request,
            template_name="teams/teams.html",
            context=context
        )

```

Removed the FakePaymentPage page object which used shoppingcart app functionality, as well as everything that depended on it. I checked the e2e test repo also, and it doesn't seem to need any of the removed code.

Updating the comment.

* conservative move to process_request
* added temp_view_func_compare metric to be extra conservative
