If ansible is run against any standalone nodes, the public set in
/root/.ssh/authorized_keys will be removed, and new connections will
fail until the VM is reset from the base-configuration snapshot if it
exists.
When deploying new nodes, ensuring the key is in the root user's
authorized_keys file in the first place avoids creating snapshots that
aren't accessible by the jenkin's user.
