Add IPv6 ci Job

Runs the BaremetalSingleTenant tempest test, which provisions
two nodes, with slaac addressing, all provisioning traffic e.g.
iPXE, ironic api traffic and iscsi happens over IPv6 on the
provisioning network. Nodes are then deployed onto a IPv6
tenant network, where tempest verifies connections between them
with ssh (again over IPv6).
