Adds uninstall script which runs the openshift-ansible uninstaller,
and only removes packages / cleans, but does not delete ec2 resources
(requires fully-installed OpenShift to work right)
Fixes #156 by separating aos playbooks and changing run's launching of
playbooks
Fixes #140, which I think may already be fixed
Fixes #53 which I think may already be fixed by the new build script(s)
