We are at the point that all distributions we are building have Python
3, so any tools running in the chroot can assume Python 3 exists.
This makes dib-python redundant; mark it as deprecated and start to
remove it from elements where it is no longer required.

CentOS 7 is the only distro we support currently that doesn't have
Python 3 installed in some form in the base images. For centos 7 add
an early install of it in the yum element so we can have all the
in-chroot scripts assume Python 3. There is only one package that
causes issues; yaml which comes from EPEL. Everywhere else it is a
base package, but we don't have a way to say "enable epel to install
this". Just hack it in, we don't want to go reworking the world for
CentOS 7 at this point.
Also add python3 and it's yaml library to the centos 8 path. This
brings in the "user" python3 in /urs/bin/python3 (the "system" python3
is already installed). Again, this just lets us assume
/usr/bin/python3 in scripts for all platforms.
package-installs is one of these things running python in the chroot,
and unfortunately we have elements that use it at 01- level in
pre-installd. Thus to make sure python3 is there nice and early, run
it at 0 level, but make sure it comes after yum/dnf update.

Other architectures are stored under "altarch" for CentOS 7, update
the match.
Convert the delimiters to "," to avoid a subtle problem with "|" --
POSIX states
Within the BRE and the replacement, the BRE delimiter itself can be
used as a literal character if it is preceded by a backslash.
So "s|\(foo\|bar\)|moo|" doesn't do what you might think; the inner
pipe becomes a literal | and this will *not* match "foo" or "bar".

Now that DIB is python3 only we can remove a hack that made sure
scripts outside the chroot ran with the correct version of python.
This is necessary as python3 does not resolve symbolic links to the
binary like python2.x did, which causes element scripts to fail finding
modules when DIB was run from inside a venv.
This patch does the following:
1. Reverts 9c7b8d1714 which was the
workaround for mixed python2/3 environments.
2. Updates the scripts to use "python3" instead of "python".

With the removal of Python 2.x we can remove the unittest2 compat
wrappers and switch to assertCountEqual instead of assertItemsEqual
We have been able to use them since then, because
testtools required unittest2, which still included it. With testtools
removing Python 2.7 support [3][4], we will lose support for
assertItemsEqual, so we should switch to use assertCountEqual.

Elements like yum and yum-minimal depend on the yum and yumdownloader
CLIs on the DIB host. We have been assuming these tools are always
installed on Red Hat family distributions but that is no longer the case
starting from RHEL 8 and CentOS 8 and Fedora for a while -- these
systems moved on to DNF and DNF does not have a hard requirement on yum.
We noticed these two tools were missing while building an Octavia
amphora image on a CentOS 8 controller node in CI:
[...] 08-yum-chroot:_install_pkg_manager:223 : sudo -E yum -y [...]
[...] sudo: yum: command not found

EPEL centos8 have different epel repos like
epel, epel-modular, epel-playground etc, so
we need to disable all not just epel.
Also ensure other epel repositories in CentOS7
like epel-testing are also disabled.

DIB was retrieving the oldest cloud image file which, presently, means
retrieving CentOS 8.1 instead of CentOS 8.2. Even though DIB runs a
system update and so catches up to latest, this takes bandwidth, time
and final image space (8.1 + system update = 765M qcow2, vs 8.2 + system
update = 518M qcow2).
This patch fixes that by taking the first image name in a descending
order list.

Since the original merge of this code
(04208e7c79) several things have
changed; particularly now we ship dib-run-parts as part of dib, not as
a separate package.
We setup $_LIB to point to the shipped library diretory via
pkg_resources lookups. We now call dib-run-parts (as mentioned,
shipped as a dib library now), source scripts, etc. via $_LIB and thus
do not rely on $PATH. Consequently we don't need this activation
part.
Which is helpful, because "venv" (as opposed to virtualenv) doesn't
have activate_this.py. So this fixes installation under that for
Python 3.
We update the functional tests to use the virtualenv_command exported
by the ensure-pip role, which will test the venv path. There is no
need for dib_python as we are Python 3 only now.

Switch to openstackdocstheme 2.2.1 and reno 3.1.0 versions. Using
these versions will allow especially:
* Linking from HTML to PDF document
* Allow parallel building of documents
* Fix some rendering problems
Update Sphinx version as well.
Disable openstackdocs_auto_name to use 'project' variable as name.
Change pygments_style to 'native' since old theme version always used
'native' and the theme now respects the setting and using 'sphinx' can
lead to some strange rendering.
openstackdocstheme renames some variables, so follow the renames
before the next release removes them. A couple of variables are also
not needed anymore, remove them.

The standard Python venv module does not have this script, so currently
DIB unconditionally fails. While a real fix will be provided in
https://review.opendev.org/#/c/704478/ this change at least allows
users to try work around the problem.
