Include tripleo container service management once

Currently this management occurs every time we include
tripleo_container_manage.  We only need to manage the tripleo container
shutdown service once during a deployment. This change moves it to a
deployment step and there is a subsequent tripleo-ansible patch to drop
it from tripleo_container_manage.
