The job has 4 nodes:
- a spine node serving as a spine switch and a place where the tempest
tests are executed from
- 2 leaf nodes serving as route reflectors to the spine node
- controller running all-in-one openstack with
ovn-bgp-agent and frr configured to peer with the leaf nodes
The job is non-voting for now to assess its stability and replaces
ovn-bgp-agent-tempest-plugin job because that job was one node only and
hence the BGP protocol couldn't be validated.
