PII Annotations are very out of date, this commit adds most that were
missing in edx-platform, and some additional annotations to the
safelist. It is not comprehensive, several other upstream Open edX
packages also need to be updated. It also does not include removing
annotations that have been moved upstream, or been removed entirely.
Those are separate follow-on tasks.
This is a helpful class when running an experiment, to help
bucket users and keep track of which enrollments to consider
as part of the experiment.

Django 2.0 will make this field required for `ForeignKey` and `OneToOneFields`.
In previous versions the option defaulted to `models.CASCADE` when not
specified. This change should make the deprecation warnings in the current
Django version go away.
The migrations where also modified, but the changes should not cause a change in
the database schema since `models.CASCADE` was already the old default.
