The edx-platform codebase already includes quite a few type annotations, but
they were not regularly checked. This may cause problems, when the annotations
themselves include errors (as we found out in some of the learning_sequences
annotations). So here, we add mypy as a dev requirement and introduce a make
command to run mypy regularly. Mypy runs on a very small portion of the total
edx-platform, as configured in mypy.ini. Our hope is that developers will add
more and more modules to this configuration file, until we can eventually run
mypy on the full code base.

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.
