Add integrated test for Ubuntu using ML2/OVN driver

This patchset implements an integrated test for a new aio_metal_ovn
scenario, which deploys the ML2/OVN driver and associated services. The
basic server ops tempest test is also included. Expectations are that
the deployed cirros VM will be reachable behind a floating IP internally
for testing purposes.

add testing for both bionic and focal
