    Default route on ctlplane in CI ipv6 nic config

    This template is used by featureset035 in CI, Overcloud nodes in fs035
    currently have no outside connectivity. Details in Closes-Bug.

    Moving default route to ctlplane for CI usecase, CI Ipv4 nic config
    template also have default route on ctlplane[1].

    It seems we created this template following the older nic template [2]
    which we use in older branches, which have two default route - one on
    ctlplane and one on external network, which seems wrong.
