I like the tasks_from approach in the snippet. Regarding tags, i'm 
currently thinking of using them to optionally update/upgrade individual 
services which make use of external_*_tasks. E.g. in an environment with 
both OpenShift and Ceph, i'm hoping we could run:

     openstack overcloud external-update run --tags ceph
     openstack overcloud external-update run --tags openshift

to update them separately if needed. That's the way i'm trying to 
prototype it right now anyway, open to feedback.
