ssh host keys question

[Sean Dilda]

I noticed on 
https://cwiki.apache.org/VCL/22-management-node-installation.html that 
some custom configs are needed for root's ssh_config around host key 
checking.

Since all of the code in VCL uses the same function to call ssh, should 
we look at modifying ssh command line used by VCL to use the '-o' 
equivalents of the ssh config options?  I think this would save users 
from having to go through an annoying setup step that their linux admins 
may not like.
