[StarCluster] Disabling hostkey checking for SSH?

[David Erickson]

Hi is there any way using Starcluster's sshmaster/sshnode commands to 
disable host key checking?
EG:
UserKnownHostsFile=/dev/null
StrictHostKeyChecking=no

I'd like to script the commands an interactive yes/no queries are 
problematic.

Thanks,
David
