Pin docutils 0.17.1

Description

While testing something unrelated, I noticed that the report generation was broken. Docutils 0.18 was released yesterday, and it breaks the old version of Sphinx we're using to create reports. I've pinned the previous version, 0.17.1, which is also what's already installed on max-exfl016.

How Has This Been Tested?

Installed this version manually into a virtualenv on max-exfl017, and checked that report generation worked again.

Dang! LGTM, but would it make sense to do a pip freeze and put everything?

Good point. I've done that in !594 (closed) - there are quite a few of them.
