The Randomized Content Block XBlock only randomizes the selection of
the children blocks and has unpredictable randomization of
the order of the selected child blocks due to the usage of sets, which
are unordered, for storing the selected blocks. This becomes apparent
when all the available child blocks in a library are chosen for a
Randomized Content Block, to randomize just the order of the child
blocks and not just the selection of the blocks. The order of the
selected blocks ends up being similar for multiple learners.
This change modifies the XBlock to store the selected child blocks in
a list, instead of a set, after randomly shuffling them.
Currently, enrollment support tool is only allowing support members
to change course enrollment only one of the two modes i.e. audit and
verified.To move a learner other than these modes,they need to ping
devops.To broaden the scope of enrollment support tool,changes have
been done so that enrollment would be changed to other modes as well.

* 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.

Ignored error where fix required changing the translated text string,
due to differences between underscore and HtmlUtils format strings.
