Updating model to only include the non-deprecated fields. This work is a follow on to ECOM-7195 and SHOULD NOT be merged until that PR is merged.
Introduces a mgmt. command that retrieves course runs from catalog service in order to update marketing urls for the courses found in course metadata cache (i.e. CourseOverview). This also provides an updated utility to retrieve course sharing url.

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.
This change adds the URL configuration and Django view required
to implement a program marketing page. It is left to theme builders
to implement a template that fulfills their own UX requirements.

pynliner imports cssutils, which has an expensive initialization. All
told, it can account for 15-20% of "fast" LMS startup (without asset
compilation). So we're going to load it locally here so that we delay
that one-time hit until we actually do the (rare) operation that is
sending a credit notification email.
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.

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.
