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undone by a later PR that merged an out-of-date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.
