This change takes the ARA report from the "inner" run of the base
playbooks on our bridge.o.o node and publishes it into the final log
output. This is then displayed by the middleware.
Create a new log hierarchy with a "bridge.o.o" to make it clear the
logs here are related to the test running on that node. Move the
ansible config under there too.
