A system upgrade broke ostestr. We can fix it by just calling stestr
directly.

We want to default to running all tox environments under python 3, so
set the basepython value in each environment.

We do not want to specify a minor version number, because we do not
want to have to update the file every time we upgrade python.

We do not want to set the override once in testenv, because that
breaks the more specific versions used in default environments like
py35 and py36.

Switch package install to Python 3 for OpenStack Rocky or later.

When upgrading, remove any python-* packages that where explicitly
installated and then autoremove --purge any dependencies that are
no longer required.

Python 3.6 is installed by default in Ubuntu 18.04 LTS.
Therefore, according to Transition Plan [1],
it'll be handy to have py36 testenv.

For more details, please check Python2 Deprecation Timeline [2]
and Python3-first Goal - Completion Criteria [3].

As of pip 10.0, --allow-unverified is not permitted.

Use of the flag in this repo was previously used to force
installation of python-apt to accommodate certain unit tests.

The unverified package, python-apt, is no longer necessary
for test execution.

All OpenStack Charms now contain identical tox.ini files,
not to be modified or made unique within each charm repo.

This is to ensure consistency across charm repos in tox
target naming, approach and purpose, also giving the
charm dev and test experience additional consistency.

Also create empty dirs with .keep files where necessary.
Some classic charms have actions and/or lib dirs, and some
do not. In all classic charms, flake will now check those
dirs to ensure lint coverage of existing or future content.

Switch to using bundletester for execution of functional tests,
leveraging tox to build out test virtualenvs.

Rename amulet tests inline with gate-*, dev-* and dfs-*
naming standards.

Update README to refer to functional testing section of the charm
guide.

The new release of charm-tools no longer ships the charm
command; update minimum version requirement and switch
to using charm-proof instead, unblocking current pep8
failures across all charms.

Also pin the version of requests to 2.6.0 until theblues
(indirect dependency of charm-tools) sort out its
requirements versioning.
