The initial version of gating playbook contained ability
to run them either on Python2 or Python3 ansible.
But it causes a lot of issues e.g. a need to install[1] both
versions of libs to support both possible ways to run,
discrepancy between local and Zuul run[2]
Zuul testing is done with ansible running on Python3 [3].
Meanwhile ppa repo for ansible contains ansible pachage
that depends only from python2. There is no package for
Python3 and we used only Python2-ansyble.
The fact that Zuul runs it with different configuration
means that we'll keep facing the issues with dependencies
in future, since Gating doesn't test it.
This patch changes makes local scripts run as Zuul.
PS
The script partially takes care of reverting intallation
from its previous runs. To cleanup completely it's possible
to run [4] in case these pacakges are not used by anyone else
