Debian defaults to Python2 which is not complete in aarch64 images.
This patch changes CI to always use Python3.

We need to install several Python modules to have working ussuri jobs.

"Failed to import the required Python library (setuptools) on primary's Python /usr/bin/python3."

And then several Python2 ones for train->ussuri upgrade jobs:

"Unable to find any of pip2 to use. pip needs to be installed."

Since haproxy is orchestrated via site.yml in a single play,
it does not need flushing handlers as handlers run will
happen at the end of this play.

Follow-up on [1] "Avoid multiple haproxy restarts after
reconfiguration".

There is no need to duplicate handler name in listen.
The issue was because we had two handlers with the same
name in the same environment.
This causes Ansible not to mark handler as already run.

Bashate warned on init-swift.sh because of E043 -- arithmetic
compound has inconsistent return semantics: (( next_port++ ))
New Zuul reported that on every change as a warning.
This is fixed here.

This change makes Bashate always produce errors so that we do not
introduce such warnings again.

The haproxy role and the site.yml file calls the
haproxy-config role to provide configuration for individual
services.

If the configuration within a service changes, the haproxy
container is restarted.

If the configuration in n services changes, there will be n
restarts. This is not necessary, a restart at the end is
sufficient.

By removing the handler from the haproxy-config role and
using the listen parameter in the handler of the haproxy role,
the handler is executed only once.

Drops support for creating Python 2 virtualenvs in bootstrap-servers,
and looking for a python2 interpreter in the kolla-ansible script.

Also forces the use of Python 3 as the remote interpreter in CI on
Debian and Ubuntu hosts, since they typically symlink the unversioned
interpreter to python2.7.
