Subject: [PATCH] Remove puppet run and workarounds from tripleo_upgrade_node.sh

For bug 1708115 and the O..P upgrade, and for the upgrade of
'non-controlers' we are now generating ansible playbooks from
collected service upgrade_tasks and these are executed instead
of the legacy tripleo_upgrade_node.sh.

To clarify, by 'non-controllers' it is meant any node for which
the corresponding roles_data.yaml role has the
disable_upgrade_deployment flag set True.

As a first pass, I am removing the workarounds from the script but
keeping its delivery mechanism for now in case it is needed still.
We can either update here to remove it or keep it until next cycle

The most important part for now is that we no longer 'manually'
run puppet here. Instead the post_deploy_steps are also collected
into a playbook and will be executed after the upgrade_tasks
(see the bug for discussion of the mechanism and related reviews)
