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.

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dashboard included the "location" field (which is obsolete) and the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.

Fix error in instructor dashboard, data download section, when trying to download a csv with the issued certificates in a spanish (es-419) configured edx-platform deployment returns a UnicodeEncodeError: 'ascii' codec can't encode character u'\xf3' in position 16: ordinal not in range(128)

More accurately, this creates a 4th shard because the
last shard is always the default.

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.

This reverts commit 60860e3a.

An `eligible_for_certificate` field is added to the
GeneratedCertificate model. This way we can retain existing grading
logic, as well as maintaining correctness in analytics and reporting.

This commit also updates the DB cache for acceptance tests.

There are 3 main changes in this commit:
* CohortFactory now sets up memberships properly, so consuming tests do not
need to explicitly touch CourseUserGroup.users to add() users.
* test_get_cohort_sql_queries has been updated to 3 and 9 queries when using
and not using the cache, respectively. This is needed due to each operation
needing an extra queery to get the CourseUserGroup from the CohortMembership.
* Adding remove_user_from_cohort(), the counterpart to add_user_to_cohort().
This is also to keep tests from touching the users field directly, and keep
CohortMembership data in sync.

There's no need to use a string literal in setattr, delattr, or the
two-argument form of getattr.
