[PATCH v4 24/24] gitlab: add python linters to CI

[John Snow]

Add python3.6 to the fedora container image: we need it to run the
linters against that explicit version to make sure we don't break our
minimum version promise.

Add pipenv so that we can fetch precise versions of pip packages we need
to guarantee test reproducability.
