Based on the log this was the Zuul executor trying to rsync files
off the job node over SSH, surprised to find the SSH host key on the
job node was suddenly different. We see this symptom from time to
time when Nova loses track of a VM somewhere in the provider and so
the IP address remains in use but also gets reassigned to a new VM
for our boot request. This is almost certainly a transient failure
and the build was merely "lucky" enough to win at rogue instance
