It may in places, but it turns out the 'value' formatter is most useful,
especially in the get_or_create_* functions where you really only need a
single value, avoids an eval or extra subshell.

    group_id=$(
        # Creates new group with --or-show
        openstack --os-token=$OS_TOKEN --os-url=$os_url \
            --os-identity-api-version=3 group create $1 \
            --domain $2 --description "$desc" --or-show \
            -f value -c id
    )
    echo $group_id
