Improvements to uninstallation playbook

This is related to https://trello.com/c/314nwSvt/58-3-uninstall-playbook

The original atomic_openshift_tutorial_reset.yml now calls the uninstall
playbook for most parts.  All the originally functionally is still intact.  The
main differences between the two playbooks is that the uninstall playbook is
careful only to delete content that ansible originally installed.
