[CI] Temporarily disable IPv6 scenario tests

We're experiencing failures to SSH into test
VMs over IPv6 IP addresses from private tenant
networks in the LVM driver job when testing
main branch code. It's possible this is a regression
in nova, neutron, neutron dynamic routing or bgp. We'll
drop this test exclusion when the bug has been
identified and fixed.
