* 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

student enrollments. We no longer need to parse the course key into an
opaque key since the opaque key class can already handle strings and the
parsing happens there. We also need to specify which course enrollment
are we editing or else the reference is lost when saving the edits.
