Amulet tests are spuriously failing due to this bug. IP addresses get
recycled as the leases expire, and the 'juju run' commands Amulet makes
fail due to the old host key being in the root users known_hosts file.

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
04:1f:98:dc:d5:aa:3a:4d:aa:d8:f6:a2:15:e5:fa:29.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /root/.ssh/known_hosts:3
remove with: ssh-keygen -f "/root/.ssh/known_hosts" -R 10.0.3.223
Keyboard-interactive authentication is disabled to avoid man-in-the-middle
attacks.
