* Remove old  performance tests that we haven't been running.

As far as I can tell, these tests to capture HAR files were created 5
years ago and not being run as a part of our suite?  They capture HAR
data that we do nothing with so even if they were running we should
remove them until we're ready to care about consuming this kind of
information.

* Update password test unicode string.
* Add ugettext translation helper function.
* Fix lambda syntax that is not valid in python 3.
* Fix ur raw strings which his not valid in python 3
* Use edx_six.get_gettext instead of ugettext.
* Fix a few other encoding issues.
* Don't use old form of sorted funciton.

This form which uses a 'cmp' method is not available in python 3.

mroytman/educator 4432 course level grade filter

JIRA:EDUCATOR-4541

* add management command to link program enrollments to users

This new API endpoint differs from the existing Grades API
in that (i) it only includes grades for users enrolled with a
ProgramCourseEnrollment and (ii) it alters its return code
depending on whether any student's grade failed to load.

* Convert to using ExitStack instead of nested.

nested is not available in Python3.

* Use ExitStack from contextlib2.

ExitStack has not been backported to the Python 2.7 standard library and
contextlib.nested is no longer available in Python 3.5.  We need to be
able to use something in both 2 and 3 as we transition so we'll pull in
contextlib2 which has backports of the full python3 contextlib.

Fix more test collection.

We stopped using it but forgot to remove it from the import.

Added edx-when's FieldData

EDUCATOR-4554
This fixes a bug where extended due dates were visible in the outline but not reflected on the courseware pages, resulting in problems not being submittable past the due date.
In order for edx-when to work on courseware pages, it has to be more careful about field inheritance, which version 0.2 achieves.
