[queens][ci][tripleo-upgrade] Network data not included in ceph-update.

Hi,

IPv6 in infrared switch to using network data recently.

We had a patch to support network-data in the required script templates[1], but for queens we missed the ceph-upgrade command which still use heat as its main driver (later version use an external-task) when doing the backport.

This leads to that error:
