Using host_prep_tasks interface to handle undercloud teardown before we run the undercloud install. The reason of not using upgrade_tasks is because the existing tasks were created for the overcloud upgrade first and there are too much logic right now so we can easily re-use the bits for the undercloud. In the future, we'll probably use upgrade_tasks for both the undercloud and overcloud but right now this is not possible and a simple way to move forward was to implement these tasks that work fine for the undercloud containerization case. Workflow will be: - Services will be stopped and disabled (except mariadb) - Neutron DB will be renamed, then mariadb stopped & disabled - Remove cron jobs - All packages will be upgraded with yum update.
