    Allow enabling routed networks on undercloud update|upgrade

    Since Rocky neutron has support to enable routed networks on
    existing an network and subnet if certain conditions are met.
    The tripleo undercloud does meet these conditions.

    This change updates the extraconfig post script that creates
    the neutron ctlplane networks. Any non routed network is
    updated to a routed network if 'enable_routed_networks' = True
    in the configuration.
