Subject: Provisioning: Retry python installation if failure occurs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Python installation is flaky and we haven't be able to determine the
root cause for it. Re-running the installation might help.
(Might) because we can't reproduce this manually.

Task-number: QTQAINFRA-3875
Change-Id: Id46d250a02e01007f03dfbb886d75b23c23a6216
