As noted, we're simply testing the default behavior of Python 3 in this
test. Remove it, now that this is the only version(s) of Python 3 we
have to worry about.

Oslo things are really server-side oriented and are heavy-weight
for client things. Remove oslo.utils and just use iso8601 and
importlib directly. It's not actually a bad library, but pulling
it and its other deps in just for a couple of wrapper methods
is a bit much here.

oslo.i18n, fwiw, is lightweight and helpful.

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.

The token_endpoint was a compatibility auth type to maintain support
for the --url global option that dated back to the beginning of
OpenStack CLI auth.  The common keystoneauth library implements
'admin_token' which provides the same functionality using
--endpoint rather than --url.

test_shell.CLOUD_2 is using an absolute path for a temp
file, so leaves /tmp/test_log_file around after the unit
tests are run.  Use a fixture instead so it's cleaned
automatically, which also removes the possibility of two
tests using the same file and interfering with each other.

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.

setUp will be automatically called around each
testcase, so this is to remove setUp that doing
nothing additional than super to keep code clean.

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
