- py35/py36 jobs are failing
python 3.6 pycache also includes links - so those also
need to be removed by tox testenv
- kolla-ansible-ubuntu-source job is failing
Without basedir set in galera.cnf - mysql_install_db looks for resolveip
in /usr/sbin, instead of /usr/bin, thus complains about cannot resolving
neither $HOSTNAME, nor localhost.
