This commit fixes a problem with the Certificates API that make it fail when trying to retrieve user certificates from courses that don't exist anymore.
The problem lies in the Certificate API not checking if the courses being retrieved by some user actually exist, to fix this, this commit improves the fault tolerance of the Certificates API.
This issue was found when investigating why a user profile page (/u/username) was returning 404's.
Turns out that LearnerAchievementsFragmentView used the certificates api to retrieve certificate information, which did not check if the course exists before trying to pull information from it, resulting in a cascade of errors that lead to a 404 on the user's profile page.

Since cert_html_view_enabled is deprecated and set default true,
PDF certificates are not appearing for learners and staff also
unable to regenerate them.

through to the REST API:
* created_date: date/time the certificate was issued.
* is_passing: boolean flag denoting whether the certificate status is
passing or non-passing.
And adds JwtAuthentication, so the Certificates REST API can be easily
accessed from Enterprise management commands.
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.

The verification workflow assumes that all verified courses will have a

enroll or upgrade.

Two new certificate statuses are introduced, 'audit_passing' and
'audit_notpassing'. These signal that the GeneratedCertificate is not
to be displayed as a cert to the user, and that they either passed or
did not. This allows us to retain existing grading logic, as well as
maintaining correctness in analytics and reporting.
Ineligible certificates are hidden by using the
`eligible_certificates` manager on GeneratedCertificate. Some places
in the coe (largely reporting, analytics, and management commands) use
the default `objects` manager, since they need access to all
certificates.
