* style: Drop unused imports.
I was looking at these files for some other reason and saw that these
imports were unused. Some of it looks like an artifact of the hoisting
of some settings up to the `openedx/env/common.py` file and others look
like some ancient unused imports.

In the effort to simplify settings in edx-platform, as discussed in ADR 22 -
Settings Simplification, this PR brings some of the production defaults defined
in `lms/envs/production.py` and `cms/envs/production.py` up to
`openedx/envs/common.py` or `lms/envs/common.py` and `cms/envs/common.py` as
appropriate.
Bringing these defaults up from the `production.py` settings modules caused
changes in the rendered settings of the `test.py` modules, and so I have
settings to the `test.py` modules to bring the rendered settings back in line
with what is has been. I have not deeply looked at which settings are needed
for tests to pass or not, but just the differences between the rendered
settings between `master` and this branch.
