Comment 2 for bug 1398488

Ok, I just took a quick look at this and we shouldn't have let the change through this way.

There are two ways to handle this ... add a brocade_ssh_hosts_key_file in this file. That is easy but hacky and bad for backport to stable/Juno.

Other option is we move this to using ssh_util for creating SSH connections. Honestly, I am not sure why it isn't already doing that. So, let me see what it would take to do that.
