* Remove full table scan of VerificationDeadline.
Before this commit, we were doing a full table scan of
student_verificationdeadline, loading the results into a giant
dict, and reading/writing that to the cache. This was fine when the
code was introduced and there were dozens of courses, but now that
we're over 12K courses, it's becoming a major performance issue for
the Student Dashboard.
This uses a subquery to the course enrollment table so that we're
only ever pulling back the deadlines to a student's enrolled courses
for any given request. It removes the cache access entirely.
If already DEFAULT Number of emails are sent, then verify that user
is enrolled in at least one verified course run for which the course
has not ended else stop sending emails

Method approve() is overridden to accommodate new users that will have their verification approved in the future.
The approve() method is called from software secure results callback every time a Software Secure Photo Verification
is approved.The method overridden now updates expiry_date and then calls super to perform task it was performing
before this change.The expiry_date set is the same as the one sent in verification approval email.
In results_callback for sspv the expiry_date and expiry_email_date for the most recent previous verification if exists
are also updated to NULL.
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.
This reworks what was done #17930, since it had to be reverted from the IDVerificationAggregate migration.
We decided to abandon that model and directly read from both id verification models.
This partially reverts commit ee1c3a4548.
The migration files introduced by the commit have been kept since they have been run
already on several enviornments.
This reverts commit 1224e341de. I've also added
NotImplementedPartitionScheme, which allows deprecated partition types to have
a valid entry point despite being unusable.
