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.

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.

Using the guideline "Course staff should have access to features related to
individual learners, but not course-wide modifications", most tools on the
student admin sub-tab of the instructor dashboard should be available to
staff as well as instructors.

Makes use of the new SUBSECTION_SCORE_CHANGED signal to trigger a task that
updates persisted course grade values. We've also renamed SCORE_CHANGED to
PROBLEM_SCORE_CHANGED to head off any issues with unclear signal names.

This management command has been broken since before the django 1.8
upgrade, so I'm deleting it and all its tests, and updating a few
other files that used these methods but are easily refactored away.
2. Add site configuration overrides to theming/helpers.py
3. Move microsite.get_value from theming/helpers to site_configuration/helpers
4. Move microsite_configuration.microsite.get_value usages to site_configuration.helpers.values

Allows multiple bulk email targets to be specified at once.
-The previous "All" option has been split into "Staff" and "Learners"
-The backend changes made here lay the groundwork for cohort emailing
-The data migration, 0005, is somewhat large and requires deploy attention
-Tests have been updated
-Numerous safe-commit-linter fixes are included
Moves ENABLE_INSTRUCTOR_EMAIL and REQUIRE_COURSE_EMAIL_AUTH from settings files
to admin-accessible configuration models. This allows for the bulk email settings
to be modified without a new AMI deploy. See TNL-4504.
Also updates tests:
-python tests mock out the new configurations in place of the old settings
-lettuce test has been moved to bokchoy
(note that there was some loss of coverage here - the lettuce tests had
been doing some voodoo to allow for cross-process inspection of emails
messages being "sent" by the server, from the client! In discussion with
testeng, this seems outside the realm of a visual acceptance test. So,
the bokchoy test simply confirm the successful queueing of the message,
and leaves the validation of sending messages to the relevant unit tests.)
-bok choy fixture has been added, to replace the settings in acceptance.py
-lettuce and bok choy databases have been updated to reflect the backend changes
The new default is to have bulk_email disabled, we'll need to call this out in the
next OpenEdx release to ensure administrators enable this feature if needed.
By default, disable all caching in tests, to preserve test independence.
In order to enable caching, inherit from CacheSetupMixin, and specify
which cache configuration is needed.
