A recent bug [0] and fix upstream no longer ensures that we use the tripleo-admin user as the ansible_ssh_user when invoking ansible playbooks against the undercloud. This means we need to update the keytab group to something else. Using root makes sense because the user invoking the overcloud installation should already have root access. In addition to changing the group, this patch updates the appropriate tasks so there run with `become: true`, allowing them to access the keytab.
