PR #21614 made this upgrade, but it was accidentally
undone by a later PR that merged an out-of-date
'make upgrade'.

We are currently running this plugin from a has directly off of master
to get support for a newer version of DJDT.  However even on master
there is not yet support for python 3.  We're running into this when
running runserver and when collecting static assets.

A quick survey of the development team at edX shows that people are no
longer actively using this debug panel.(14 responders all saying no to
the question "In the last year have you used the mongo portion of the
django-debug-toolbar in edx-platform?")

This makes sense since the module store and courseware related
developement is not very active right now.  Given all this, I'm removing
this toolbar for now and if we need it again we can survey what's
available at that time to choose the best tool.

Unfortunately snakefood is not supported in python3 so I'm removing it
and the tools built on top of it for now as they are not in active use.

If you're looking at this wishing it still existed,

The 2.3.0 ORA-2 release did not regenerate .min.js
files, so the changes did not appear on Stage or
Production.

The ora2 upgrade increases the assignment upload
limit from 10MB to 20MB.

Due to a request from a Master's partner who reports
that the current 10MB limit is not enough for their
degree programs.

* Update Financial Assistance logic

Use the zendesk proxy app instead of the unsupported zendesk library.

* Move to pre-fetching the group IDs.

Rather than making extra requests to zendesk to list all groups and find
a specific group ID. Just make a pre-filled list of group IDs for the
groups we care about.  When a group name is passed in, it is checked
against this list and the ticket is created in the correct group so the
right people can respond to it.

Fix for test that broke related to DRF;

* 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.

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.

Update the version.
