Use OVS with IPv6 data path testing jobs

We run IPv6 data-path tests with LVM and
Ceph-NFS drivers by setting up bgp to
advertise tenant network routes to the host.
Bug #1959666 prevents the use of OVN with
neutron-dynamic-routing. The underlying neutron
ML2 mechanism driver doesn't matter to
manila; so lets use OVS in the meanwhile with
these test jobs.
