    Update/upgrade commands for services with external installers

    New `openstack overcloud external-update run` and `openstack overcloud
    external-upgrade run` commands are defined. These are meant to perform
    updates and upgrades for services deployed via
    external_deploy_tasks. A separate command is used because external
    installers don't fit well within the --nodes and --roles selection
    pattern we've established for the normal `update run` and `upgrade
    run` commands.
