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.

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.
