* API endpoint for certificate generation, an authenticated post with course
id requests that grading be carried out and a cert generated for
request.user in that course, using the usual grading and certificate
machinery (ie, it does not imply whitelisting, though whitelists and
blacklists will be respected)
- Logs each request as it comes in
- Calls xq.add_cert() and consequently, does grading synchronously on
this app host and then queues request for certificate agent.
- example usage:
```
curl --data "student_id=9999&course_id=Stanford/2013/Some_Class" http://127.0.0.1:8000/request_certificate
```
* Studio advanced setting added, "certificates_show_before_end", which
determines whether a course should permit certificates to be downloadable
by students before the coures's end date has passed.
- Modifications to dashboard view and templates to allow display of
certificate download links before course has ended.
(XXX: may declare failing students as failing before the course has ended.)
- To test, turn the setting on in a course which hasn't ended yet, and
force certificate generation for a student, then check their
dashboard.
Support incremental conversion of events from the old API to the new, in order to ensure the new system is working, enrollment events have been modified to make use of the new API.
Also improves handling in cases where account creation did succeed, but
comments service user creation did not.
Depends on commit 88abdd8a0b20bc9816f487b25abdea1953f5661d in https://github.com/edx/cs_comments_service

This is necessary to allow non-browser-based services (e.g. notifier)
to know a user's preferred language even if the user has not explicitly
selected one.
Allows specification of countries to embargo, what course(s) should
apply embargo restrictions, and whitelist/blacklist capability for
specific individual IP addresses.
Adds configurable middleware in common/djangoapps/embargo that
allows specific courses to comply with US Export regulations by
embargoing students from specific countries, whilst simultaneously
allowing other courses to be freely open to all.
