Run online migrations via "external-upgrade run"
This will pull the online data migrations out of the upgrade
maintenance window and let them be performed after the main upgrade
phase while the cloud is already operational.
The online part of the service upgrades can be run using:
openstack overcloud external-upgrade run --tags online_upgrade
or per-service like:
openstack overcloud external-upgrade run --tags online_upgrade_nova
openstack overcloud external-upgrade run --tags online_upgrade_cinder
openstack overcloud external-upgrade run --tags online_upgrade_ironic
