This modifies the lang-pref django app to:
a) Use the current value of the 'edx-language-preference' cookie to set the
users Accept-Language header on an incoming request.
b) At the end of the request, update the 'edx-language-preference' cookie
to reflect the users current Language Preference choice, if any.

When using the `org` option with the bulk_change_enrollment command,
the command should not exit if it encounters a course which does not
have the given `to_mode`.

Add a new waffle switch that allows us to assume zero grades for
learners who have no entry previously recorded, and another to
disable persisting grades for unengaged learners.

The (now deprecated) programs service had several fields to set up configuration of the API. We are removing the property/field references in codeas the first part of deprecating the model fields. Also being removed are the model properties.
Before this commit, we had to do a separate query for every course a
user was enrolled in when determining whether a course was refundable
(if you have a certificate, it isn't). Now the student dashboard will
make a one-time query to grab all of a user's cert-issued courses. This
is indexed, so it should be much faster than grabbing each one
separately.
Pre-load the course overviews attached to CourseEnrollments on the
Student Dashboard, if possible. This will only grab the CourseOverviews
that already exist, and will not generate new ones. Any missing
CourseOverviews fall back to the lazily-created one-at-a-time behavior
they've always had. That's mostly because I wanted to optimize for the
common case in the least invasive way possible, and I don't want to get
caught up in locking issues.
There are a number of Django Signals that are on the modulestore's
SignalHandler class, such as SignalHandler.course_published. These
signals can trigger very expensive processes to occur, such as course
overview or block structures generation. Most of the time, the test
author doesn't care about these side-effects.
This commit does a few things:
* Converts the signals on SignalHandler to be instances of a new
SwitchedSignal class, that allows signal sending to be disabled.
* Creates a SignalIsolationMixin helper similar in spirit to the
CacheIsolationMixin, and adds it to the ModuleStoreIsolationMixin
(and thus to ModuleStoreTestCase and SharedModuleStoreTestCase).
* Converts our various tests to use this new mechanism. In some cases,
this means adjusting query counts downwards because they no longer
have to account for publishing listener actions.
Modulestore generated signals are now muted by default during test runs.
Calls to send() them will result in no-ops. You can choose to enable
specific signals for a given subclass of ModuleStoreTestCase or
SharedModuleStoreTestCase by specifying an ENABLED_SIGNALS class
attribute, like the following example:
from xmodule.modulestore.tests.django_utils import ModuleStoreTestCase
class MyPublishTestCase(ModuleStoreTestCase):
ENABLED_SIGNALS = ['course_published', 'pre_publish']
You should take great care when disabling signals outside of a
ModuleStoreTestCase or SharedModuleStoreTestCase, since they can leak
out into other tests. Be sure to always clean up, and never disable
signals outside of testing. Because signals are essentially process
globals, it can have a lot of unpleasant side-effects if we start
mucking around with them during live requests.
Overall, this change has cut the total test execution time for
edx-platform by a bit over a third, though we still spend a lot in
pre-test setup during our test builds.

We need to be able to track which site a given user account was created on. This
change will create a UserAttribute model with a key of 'created_on_site' and a value
containing the domain of the site on which the user accounted was created.

Modify CourseEnrollment.enrollments_for_user to select the related user
object. This saves us from a bunch of redundant queries on the student
dashboard.
This adds functions to the catalog utils which munge data
collected from the program endpoint and LMS database to construct
data structures that are ready for use by view and templates
related to the Open EdX marketing pages that live in LMS.
