We had this library capped at a release that is a few years old. Now
that we have dropped py2 testing, we can pick up the latest version.
This uncovered a few things to clean up. Mostly the fact that mock is
now a part of the StdLib unittest since Python 3.3.

In reviews we usually check import grouping but it is boring.
By using flake8-import-order plugin, we can avoid this.
It enforces loose checking so it sounds good to use it.
This flake8 plugin is already used in tempest.
Note that flake8-import-order version is pinned to avoid unexpected
breakage of pep8 job.
Setup for unit tests of hacking rules is tweaked to disable
flake8-import-order checks. This extension assumes an actual file exists
and causes hacking rule unit tests.

this will better isolate the unit tests from the functional tests.
unfortunately, the "integration" tests had to be lumped into the
"unit" tests since we need the separation in testr.conf
