Basic architecture of Maintenance App - SUST-19, SUST-42. Implement Force Publish Course view. SUST-46

Adds cohorts as valid bulk email targets.

TNL-4356

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

If we pass non-ASCII strings to create_csv_response, it will call
unicode() on it, and fail with UnicodeDecodeError.  So pass Unicode
strings, or ASCII-only bytestrings for the headers.

Add bokchoy test and changes in html

OSPR-1155

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.

OSPR-1155

The student profile report that can be downloaded from the course staff
dashboard included the "location" field (which is obsolete) and the
mailing address, which is seldom completed. Here, we add the "country"
and "city" fields to the csv report. To do so, we need to be able to
dump the new fields to JSON so we convert the user fields to unicode
when needed.

Note that this breaks compatibility with earlier reports.
