This switches the bridge name to bridge01.opendev.org.
The testing path is updated along with some final references still in
testinfra.
The production jobs are updated in add-bastion-host, and will have the
correct setup on the new host after the dependent change.
Everything else is abstracted behind the "bastion" group; the entry is
changed here which will make all the relevant playbooks run on the new
host.
