    Fix upgrade failure due to missing repo containers

    Commit 368b7e2b0ef5abf792373f232087d0a4e595a5b9 has introduced a bug
    causing the upgrade script to fail when running the playbook
    mariadb-apt-cleanup.yml. The failure happens because the repo containers
    no longer exist and so the playbook fails to connect to those
    containers.

    This commit modifies the hosts targeted by mariadb-apt-cleanup.yml to
    remove the repo containers.
