This patch modifies the existing openstack upgrade tests so that they work with focal (by explicitly supporting mysql-innodb-cluster), and are also interruptable and resumable (at a charm level). It also makes them work with the udpated 'get_upgrade_groups()' that ultimately gets a List of Tuples rather than a dictionary.
